I just switched to the 7/1 BMS test kernel, and so far, it is very stable. Hopefully this helps figure it out. I like the additional options I get with QK!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] PwnCakes193:
Yep. Working on it now. Using stock CM config layout now so the kernel will be giant but hopefully that resolves whatever issue everyone is facing.

Lots of theme manager updates in the latest Carbon source so I'm going to sync and build now. Have new kernel goodies at the bottom of the post so install that!

http://d-h.st/2Dg

Try it out again. Hopefully that fixes it.

[MENTION=1683096]PwnCakes193[/MENTION] - would be very appreciative if you could take a look at the bluetooth issues I had before with Carbon/Quantum. I'd love to get back on Quantum - it's blazing fast - but it's a deal breaker with bluetooth not working in the car.

thanks in advance!

by the way - with 7/1 (Antutu 16950, Row 1024, Cubic, Intelliactive - rest defaults) i noticed 6.6% gain in performance from the 6/26 kernel.

EDIT: 7/3 rocking 16920 as well! THANKS!

Doing that now. Was on TWRP 2.7 flashed 2.7.1. Still didn't work. Error says "Error executing Binary in zip" I have this on my extSD card, I'll move it to the phone and try.

UPDATE: Location Change didn't help
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] MJPollard:
FWIW, I stayed on TWRP 2.6.3.1 and have yet to encounter a single issue with any zip I've tried to flash (though to be honest, I haven't tried to flash the new kernel yet, but I'm not anticipating a problem). I don't trust the 2.7 branch yet, after reading about the various issues that people have had with it; I'll stick with something that's tried and true!

Can't talk for everyone, but I've had no issues with TWRP v2.7.0.0 and 2.7.0.1. What are the issues people are reporting? :S
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] MJPollard:
Can't quote specifics, but I do remember people talking about them back when 2.7.0.0 was released. (The release for the Nexus 10 was particularly nasty, as I recall, with people unable to restore backups, among other things.) They may be resolved now, but I'm still a bit gun-shy. :) Don't fix what ain't broken, right?!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] hizhonor:
Sorry to report that after flashing Quantum 5 - 7/1 (coming from CM) the "com.android.bluetooth has stopped" errors have returned. It seems to coincide with tapping "Yes" when granting access to messages. Once the Bluetooth cycling starts, I never get the request to allow access to my contacts, so the phone book stays empty. Although call history seems to come across.

The car is a 2014 Mini Countryman with their latest software installed.

I'll continue to trouble shoot to see if I can stumble upon any thing else.

I'd be happy to provide a log if it would help ( and told which one :confused:)

Ah okay. Might have been device specific. Agree with you though, sometimes peace of mind is great.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] MJPollard:
Exactly. Since 2.6.3.1 works with everything I've thrown at it (to date), I'm just going to stick with it until the time comes when I have no choice but to upgrade, or I get a new phone. :D

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] therebel88:
Same exact issue in my car (Infiniti). This has been a problem with Carbon for an eternity. Was actually one of the reasons I stopped using Carbon. It's definitely not a Slim issue either as I never had this problem in Quantum 4.x . I've asked the Carbon devs to look into for so long and they never have. Which is at this point a deal breaker for me, as bluetooth works without issue in CM, PA, AOKP, Slim...so there's no excuse in my opinion for it not to work in Carbon.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] kangtastic:

Same problem with Carbon and my Ford Focus. Started with something they changed back in March. Worked fine before that. Kept bringing it up to them on Google+ but nothing was done.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Peterbluez:
I was getting a bunch of the SELinux related reboots like everyone else. Haven't had a single problem with this new kernel, though. Its syncing with my car beautifully, stable and solid, low battery usage, all the stuff we know Pwn is good for. Good show, old sport!

My one issue/request is the CM profile chooser. I'm using a tile in the drop down to select profiles, but really like to use the power menu for it. I looked in the carbon fibers but that isn't an option (at least so far as I can tell). Is it possible to build that in? If not, it isn't a big deal at all - sorta like asking if this diamond couldn't be a bit shinier.

Time to go buy some oversized fireworks!!

Uh-oh ... Not good.

I did a little more testing and find that if I decline access to messages, I do get prompted for access to contacts. So right now, I have a populated phone book and the connection seems stable. I'll leave it like this and see if Tom can work his magic where others have apparently chosen not to invest the time.

Only one reboot so far for me. SD card does not work (64GB), although is readable from recovery. The rest is working good.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ganjah:
Didn't want to keep posting reboot logs, but things have slowed down a little bit. I tried the latest 7-3 kernel and it didn't eliminate reboots, but it has kept them to a minimum.

Of the four reboots I've had on this kernel in 16hrs, none were during heavy usage. During the most recent one I was checking the Emergency Broadcast settings in the stock messaging app, it locked up for 15s, then rebooted. Can't pull a last_kmsg at the moment.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Peterbluez:
I'm getting a very reliable reboot any time I install something from the playstore. I've tested 6/28, 7/1 and latest 7/3 QK with Quantum 5, each with a full wipe. This means, I can't install anything new from the playstore. I've reinstalled the pa_gapps-modular-mini- 4.4.3-20140608-signed.zip - thought the problem may be the 4.4.3 gapps, so I tried pa_gapps-modular-mini-4.4.4-20140629-signed.zip. Same problem. Apps download fine, but the phone reboots while installing.

Two other issues I've had - First, I have only been able to see my external SD card after installing Pwn's Exfat.zip (I think that's the file) from a month or so ago. Again, this happened on the three different QKs paired with Q5. Second - I can't seem to get ART to work (on the 7/1 or last 7/3 QK). It acts like its going to work, but ultimately ends up in a boot loop.

Certainly not complaints, just trying to help with the development here. I'm happy to post kmsg's if they'll help.

edit: SD card is 16gb exFAT.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Helloworld294:
FINALLY someone with the same problem as me. My 64GB isn't readable as well. It's formatted as exFAT.

Although its accessible through recovery.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] PwnCakes193:
You have something installed like Xposed that blocks ART. So fix that and you're good to go. As for the reboots, just use a different kernel for now like DKP or BMS. I'll be working on it and should see something up today or tomorrow.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Helloworld294:

I'm not sure what you mean by the other 2 7-3 kernels. I only see 1 link on the first page of this thread for the kernel.

I didn't Odin back to stock before I flashed the ROM, but I did wipe cache, system, dalvik, and factory reset before I flashed. I thought that was enough for a clean flash.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Subsonic44:
Go here and choose the latest 7-3 or maybe even try the 7-4 kernel (I think 7-4 was just a fix for exfat on sd card).

Yes I am. I'm back on the 7/3 QK. I had switched to BMS as it is very stable, but just doesn't give the "deep sleep" that QK does. On the 7/3 QK, I get a rare reboot, but its much better than the 7/1 version.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] PwnCakes193:
Everyone should use the 7/4 kernel for now. Tell me if it reboots and whatnot.

Okay, that's sounding reasonable . I've been on qk all the way, and apart from the occasional reboot, which I can live with, everything else is, as someone said, buttery smooth :) Maybe I'll try 7/4,but I'm content to hang in till Pwncakes corrects it.
