Does it still crash when sleeping when the wifi is left on after doing a wipe data/factory reset?

If so, is it a hard reset (back to lenovo logo) or a soft reset (back to cyanogenmod logo).

If it's a hard reset, could you provide the contents of /proc/last_kmsg after you had to force it to reboot please?
[Miscellaneous Android Development] jpisini:
So still can't get on our wireless network. Battery life is less than half of what I was getting on 04/07/12 .
[Miscellaneous Android Development] rhay:
How about the front camera, still upside down?
[Miscellaneous Android Development] passy:
I think You had the same sutiation as mine.

Do You have WiFi ERROR ?

In my case it happened when I restored backup from february (via CWM). Clearing cache (dalvik also) didn`t help.

I upgraded to 0205 rom and it`s working now.
[Miscellaneous Android Development] gmarkall:
Ah, you've just reminded me that cwm doesn't back up the kernel. So you will get odd errors from restoring backups unless you flash the nightly that you were running before the backup first.
[Miscellaneous Android Development] gregtsai:
boot failure

After flashing the 0515 update, my A1 won't boot into cm7 and stuck on lenovo logo and keeps rebooting. It never went into cm7 logo.

I can still boot into clockworkmod recovery and apply zip updates and i tried factory reset and re-installed fast boot and cm7 update zip and then wipe data again, but still won't boot into cm7.

What can I do and check to fix it?

Thanks in advance!
[Miscellaneous Android Development] bejay:
Reboot and hang

Had another hard reboot this morning. I enabled wifi, went online and started browsing. As the web browser loaded, my A1 rebooted back to the lenovo logo. I allowed it to reboot and then powered it down using the long press menu.

Got to my office and powered it back up and it hung on a black screen after the Cyanogenmod logo (all backlights on), I tried holding down the pwr button for 10 sec and then tried again, got the same thing, hang after CM logo.

I left it 5 min as it does soething similar after flashing a rom but eventually boots.

After 5 Min it still hadn't booted so I held down pwr for 10 sec and them tried to boot into CWM with pwr and vol-. It loaded to the first lenovo logo and stayed there, took 3 attempts and eventually holding down pwr for 30 sec before it would boot to CWM. Once it was in CWM I rebooted from the menu and it booted normally.

I'm still on the 0510 build. last_kmsg
[Miscellaneous Android Development] gmarkall:
Is that the same last_kmsg you linked to the other day?

Are you able to get one from immediately after restarting? It gets overwritten by each subsequent reboot, so this one doesn't contain the details of what happened immediately before the restart that you described.
[Miscellaneous Android Development] purloiner:
Hi all

Last night I had a weird issue, here's the last_kmsg fwiw.

http://pastebin.com/mDc2ERyG

The screen was blank as the device was asleep, I pressed the power button to wake it, the keys lit up but the screen didn't light up, I got the impression it was still alive though. I don't have my adb equipped computer with me so I grabbed the log via shell and stuck it into evernote so I didn't loose it.

I had to power off to recover.

Cheers

No wireless works we have to click a check box to connect to our wireless network to agree to terms and this box.doesn't show up.
[Miscellaneous Android Development] bejay:
No, it's from this morning, I just posted it to the same place. I shut the machine down immediately after the forced reboot, that is from after the next boot. I'll make sure I get one immediately after the reboot if it happens again.
[Miscellaneous Android Development] ssjfjs:
Yesterday, I switched the setting to switch wifi off when screen off and charged my device. Everything was fine in the morning and it was completely charged. I unplugged the power supply and and left it running over the entire day. When I came home I tried to unlock the screen but nothing happened. So I forced it to reboot and I saw a lenovo logo and the device rebooted several times. I switched it off and on and it booted normally into CM7.

I attached the /proc/kmsg. hope it helps.

cheers
[Miscellaneous Android Development] milaq:
for now u could use the stock (and hacked) /bin/vold to get the internal sd working.

dont forget to apply the correct permissions though (root.root@755)
[Miscellaneous Android Development] xbdesign:
How did you do that?

Did you install ROW and afterwards your backup?
[Miscellaneous Android Development] gmarkall:
New version

The download page is now updated with pati-'s fix incorporated into it, and a few libs milaq pointed out were missing. This stops the reboots, and fixes the accelerometer.
[Miscellaneous Android Development] xbdesign:
Just testing it, looking gooood
[Miscellaneous Android Development] purloiner:
No I did backup before installing CM7, to restore I just did a factory reset and restored the nandroid. Ignorance is bliss...
[Miscellaneous Android Development] purloiner:
Thanks Milaq do I just copy that file from the stock build and set up perms and reboot?
[Miscellaneous Android Development] gmarkall:
I think (based on what Milaq has said on IRC) that that should work. If you have the files in the current directory, something like:

adb remount
adb push vold /system/bin/vold
adb push vold.fstab /system/etc/vold.fstab

should get the files copied over, then

adb shell
chown root.root /system/bin/vold
chmod 755 /system/bin/vold
chown root.root /system/etc/vold.fstab
chmod 644 /system/etc/vold.fstab
sync

should get the permissions set up and sync the filesystem. Then, try rebooting.

Disclaimer: I haven't tried this - hopefully it's correct, but if it's not, then I hope it provides the general idea.

Am I the only one who would want the internal card mounted as default?

Cheers
[Miscellaneous Android Development] gmarkall:
I'm not sure - I'm surprised it didn't happen at boot.

I think that's what everyone would want - it's my goal to get it working in this way.
[Miscellaneous Android Development] purloiner:
Sounds good I will Google for a workaround, until then I will just manually start hold. I shall use this ROM permanently and see how it goes.

Thanks again!
[Miscellaneous Android Development] unplugged138:
you can install this app : autostart.apk

and

mkdir /data/opt

put autostart.sh in /data/opt

chmod 777 /data/opt/autostart.sh

reboot A1

Give autostart.apk Android superuser permissions (yes, root is required) when it rebooted
[Miscellaneous Android Development] unplugged138:
NO,I have a 2GB Lenovo A1 and I want the external SD card mount as /mnt/sdcard,

so I can install big apps with big data packages.

thanks again.
[Miscellaneous Android Development] xbdesign:
In my first Test I found that WiFi would only work if you dont turn it off an on again. If I try that, I get an Error trying to turn WiFi on, after 3-th try it crasches down. I allso found that Vibration and GPS dont work.

I allso have 16GB external-Card that ist shown as 8 GB.

I allso tryed going back to booth Stock ROM's and restoring mine backuped Data.

No Problems at all.
[Miscellaneous Android Development] gmarkall:
Thanks, I didn't realise that it makes more sense to use the external SD card when you have a 2GB Ideapad. It seems like there's a way in CM7 to switch the internal and SD cards (the ro.vold.switchablepair property). I'll have to see if this can be made to work - the stock Vold contains some dirty hacks, so it might take some work to get things behaving properly in CM7.
[Miscellaneous Android Development] unplugged138:
yes,the stock vold be hacked by lenovo,maybe hard code the configure within the vold source code .

swich the internal and external sd cards by modify vold.fstab?

Battery life

I'm on 1.2 Ghz and Wi-fi allways on for 3 days and life battery is definetly worst than before.
[Miscellaneous Android Development] jouwheld:
I also experience this sometimes with the latest nightlies.
[Miscellaneous Android Development] DroidZombie:
DSP noise

I was having similar noise problems that others have mentioned. Buzzing after exiting applications and bad static through the headphones.

I went into the application manager and cleared all the data for DSP manager. Suddenly I didn't have any more buzzing and the static was pretty well gone.

Anyone have any ideas as to why this worked?
[Miscellaneous Android Development] bren924:
I have had horrible battery life when I try upgrading to any of the nightly CM7 builds the past few days. I've actually kept the 5/1 build as my working build, as most of the new nightlies drain my battery within 24 hours (and that is with the tablet screen off and basically not in use for about 18 of those 24 hours). Prior to this I was getting anywhere from 3-5 days of battery with mixed usage. Something seems to not be agreeing with my A1 in the new nightly builds.
[Miscellaneous Android Development] sputnik3:
I'm seeing the same thing with the 1005 build. I lose about 1/3 of battery life overnight.
[Miscellaneous Android Development] mikelets456:
On the 5/7 build and left my Tablet in the car yesterday while on a plant inspection: Took off charge at 7:30 AM, tablet sat idle until 4:30 PM and was at 96% when I checked it. When I got home I used it on and off for a few hours and when I went to bed at 10:30 PM it was at 83%.
[Miscellaneous Android Development] bren924:
I'm back on the 0501 nightly and battery is back to what I like to see, only lost about 7% in 9 hours.
[Miscellaneous Android Development] bejay:
Could those of you that are having battery life problems check/report what you're wifi sleep policy is set to.

On my A1 running the 0510 build having the sleep policy set to never prevents it from going into deep sleep, it's constantly awake just the screen is off. If I manually switch wifi off before putting it to sleep, it works as expected and I get good battery life.

perhaps someone else could confirm this behaivour? Might help the developers figure out whats going on.

I use better battery stats to check whats happening, I'm not sure if there is a free version but I'd imagine theres something similar.
[Miscellaneous Android Development] bren924:
My policy is set to sleep when screen is off. I have always used this setting.
[Miscellaneous Android Development] jpisini:
Mine is set to when screen turns off.
[Miscellaneous Android Development] mullepol:
I'm having the same problem as purloiner and jouwheld with the screen not showing anything. I'm using a nightly from this week, although my previous version was from March, so I'm not sure when the problem started.

I also noticed that the screen would not shut off properly. Instead it went blank, but the backlight was slightly lit up. I have now wiped the firmware and started fresh. I'll report back if it reoccurs.
[Miscellaneous Android Development] gmarkall:
Still trying to get my head around this one. I noticed it on my own a1 as well, but it doesn't happen that often so its tricky to test.
[Miscellaneous Android Development] bejay:

[Miscellaneous Android Development] gmarkall:

wallpaper changes not sticking

I got my A1 on Saturday the 19th, and finally got it rooted and CM7 installed today. Like it so far, there's only one glitch I've noticed: when I change my wallpaper, it reverts to CM7 default after a reboot.

Thanks to the devs for all your hard work! It's much appreciated :)
[Miscellaneous Android Development] Neuralgia:
Do you charge with a computer?

Maybe your wallpaper is stored at your sd card, so when you plug your a1 the card gets unmounted
[Miscellaneous Android Development] GTOgirl:
My wallpapers are stored on my SD card, but when I have my A1 connected, I don't have USB storage turned on unless I'm moving a file. The wallpaper stuck this time around, though. Weird....
[Miscellaneous Android Development] gmarkall:
From your last_kmsg:

pm_op(): platform_pm_suspend+0x0/0x94 returns -38
PM: Device mmci-omap-hs.2 failed to suspend: error -38
PM: Some devices failed to suspend

This seems to be where the problems begin - mmci-omap-hs.2 is the mmc host which the wifi chip is attached to. I guess it's failing to suspend because without CONFIG_LENOVO_BCM4329, the removal of the wifi chip from the mmc bus is not forced.

I'm not sure if this is happening on lots of A1s but only crashing yours - does anyone else have lines like these in their /proc/kmsg or /proc/last_kmsg, regardless of whether the A1 is stable or unstable?

I'll see if I can figure out how to stop this - please bear with me :)

CM7 is fine

installed CM7(day 5.10) yestoday, it's quite nice.

some issues:

1. front camera still upside down, after all these days... i bet it has sth. to do with the gravity stuff, just instinc though.

2.is there any settings/configurations somewhere for those three button lights? i actually like it better that they stay on all the time, but it is always good to know if there is another option.

3.find many linux tools in /system/xbin, including hciconfig, hcitool, rfcomm, etc. they all work, well, mostly. when tring to bind a bluetooth device the command "rfcomm bind /dev/rfcomm0 <MAC> <Channel>" gives sth. like this: "Can't create device: Operation not supported on transport endpoint", it must be a kernel issue then?

Wifi status

The changes to the wifi drivers are causing far more problems than they're solving, so all the wifi stuff has been reverted to its pre-May 10th state, which is pretty much as they were given to us by Lenovo. Should be in the next nightly build that appears.

I'll continue to work on trying to make the wifi work 100% stably on all A1s, but I won't be doing it as part of the nightlies anymore because its too inconvenient.
