Calm down, it was just a question in case you're still knowing what you had changed in your Test 2 kernel which solved the drain.

well, decided to use SuperSU and it f'd up - worked for a short time but not now. i appreciate the effort however i also desire to use whatever su i desire.... worked for a day or so, now supersu won't allow me to select/de-select anything (i purchased supersu pro).

again i do appreciate the effort put forth on this dhollmen rom, but after 2 days dealing with it may take a while for me to come back.

BTW: this is a great rom, after the install everything necessary is available (follow the instructions!!) and it boots so quickly! i swithced to supersu, worked well for a few hours but not working now - supersu will not let me allow access (the buttons will not work = su 2.40) . i'm so tired of superuser and i prefer supersu so this one may be a bust for me.

i'll keep checking though to make sure if it is a dhollmen or supersu issue (alreadly contacted supersu, already re-installed 3x, tried various tb recoveries & without installing backups - still the same result!).

later.

tried fasterfix gps also, not working.. no superuser is working atm..

will try again next week (i work fri-sun), but not looking good..

On Slimkernel i was able to watch it but it was laggy but now I cant at all

also Cant connect to Camera

maybe the Rom is not supported, but I installed this rom because its using less RAM :) Thank you

As you can read, some bricks happend on L, it might be old devices, flash memory won't live forever, but i take the reports serious. There are not many reports if you see the amount of downloads, but only 16gb models which pointed me.on the MAG2GA TRIM bug.

Something might have changed on L our tab doesn't like.

I noticed that the kernel handles sysctl.conf for itself, is there still a way to disable ipv6 ? as it causes issues on my network.

I tried adding sysctl.conf to sysyem/etc with the line: net.ipv6.conf.default.disable_ipv6 = 1

but after reboot term is still showing it as not disabled. Any help will be appreciated

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] JoeSyr:
Well, if Andi's getting out of the game (thanks for all the hard work btw!) I just thought I'd mention something else here, don't know if this has anything to do with the kernel, but my device stopped booting today on Omni 5.0 so I'm back on 4.4. Some details on it posted in the Omni thread (Link).

If there's any value in restoring my backup from that occurrence and trying to get some sort of log (last_kmsg? Not sure if that would apply to this type of issue, can't boot into system but I think I can get that from adb in recovery, if it would contain info from the failed boot sequence) I can put that on my to-do list, would love a stable 5.0 setup but for now 4.4 is fine with me.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] tuxafgmur:
All Right. Thank by your information.

First, I am glad your problem is solved.

If the tablet can boot is because nothing happens and Rom can always be reinstalled.

About the famous bug, think I am totally skeptical today (not that the bug exists, but it exploded these days). Might be tomorrow I think otherwise.

In my humble opinion, Lollipop has too many loose screws yet and many times users think that new is better. My phone continues with the latest ICS. We are working with very refined Kit-Kat versions, but we remember how bad it was at first?.

If understand you, may be you like another test installing my kernel.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] CSP III:
User beware right???

I agree with you Tux.....too many variables, issues, problems etc for any kind of stable, user friendly, LP experience on these Tabs. There has always been many different this and that issues through out the last couple years in regards to the Tab 2 that i just cant see the point of continuing on in the hunt for perfection with them. I've played around a little with the various new LP builds and after much frustration, have decided that for me, and my Tabs, 4.4.4. is it. Its the best that I will squeeze out of these poor old things. They all (3) have different KK Roms running and they all are smooth, quick and most importantly for me, stable. When its time, I'll move on up the upgrade ladder and take it from there. Your hard work, as well as Andis' and Markos have made my Android experience exceptional, and with out it, My tabs would have been retired many many days ago. Thanks to you sir....I'll be a lifelong follower of you all. The work speaks for itself.

@Android-Andi:

Undoubtedly, the kernel has not blocked his tablet.

About the issue:

The more laps I give, the matter the more convinced I am that it is not necessary to integrate recent kernel patches about MMC issues.

In fact, right now, think Dhollmen kernel will not end the week with them inside.

I'd appreciate it, may temporarily, if you retire the Recovery performed in "Lollipop mode" since possibly they are not needed (have not checked what they bring).

I wonder how the problems started with Lollipop or the last Recoveries?

Wait for your comment

It happend on old and new recovery,

So i don't think it has to do with

BOARD_SUPPRESS_EMMC_WIPE := true

As different kernel in those roms used, it isn't related to kernel pvr because on cm still using it as module.

There's nothing changed on device tree or kernel since KitKat that could explain the issue.

I haven't compiled any recovery inside L source because it's getting to big, had to compile on KitKat source.

I think it is a Lollipop issue, not recovery.

Edit:

As you can see, only MAG2GA chips affected.

Edit2:

Could it be an GCC 4.8 issue?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] tuxafgmur:
@Android-Andi:

About BOARD_SUPPRESS_EMMC_WIPE:

Do not worry about this. Not needed and not used anywhere.

I made this commit to Dhollmen Rom.

You can do the same in the other Roms.

About PVR:

PVR does not intervene here, either as module or inside the kernel.

About RECOVERY:

Until this is clarified, I will recommend exclusively use TWRP-2.8.0.5 mine or TWRP-2.8.0.1 yours as the are the same.

About MAG2GA:

Trim bug was adressed already may 2012 (FREV 5)

Codeworks included the patch at the appropriate time.

About Lollipop:

It seems the trigger, but only the kernel controls the Harware

About GCC-4.8:

Obviously, I do not know

My opinion:

I included the latest patches, that you have built, entirely non to sow more doubts to users.

Since I did, doubt keeps me constantly, thinking about it.

We need to TRIM eMMC or performance will be seriously degraded.

During this day, hope, will revert the pacthes and leave Dhollmen Kernel as was before

I will not take more responsibility but I use in my own device (incorporating this chip)

If from there, users choose not to use my products, it is his right and his decision.

Obviously, if they use it, they will assume the risk of my error.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] CSP III:
Please. all end users. My suggestion, for what its worth, is to revert back to your most stable backup and live with that. There have been too many variables with all the various CM12, LP, Dhollmen ROMs and Kernel combos people are trying to make for a enjoyable user experience. Most likely, and again this is my opinion based upon being around here and experiencing most all from these Tab2's for the past couple years, is that these TABS are totally different from one to the next. Meaning, what works for some does not mean it will work for others. Its a strange thing, it an annoying thing as well but the facts to support my claim are in all of these Tab2 threads. Check them out, read back thru the endless pages and you will see for your self. The best example I can give would be the dreaded "battery drain" I've tried all ROMs and Kernels through out and have never ever had it but many did and some of you still do. Another is this BLOB thing. I have, as well as others, have never experienced the issues being reported over and over, but many others have.

Andi, and Tux are petty much done here so support will be very limited if at all. Most likely, and sadly for some, 4.4.4 will be the best and most stable that there is for the Tab2's. Some will be able to roll with 5.0, some not. I am one of the ones whose 2 tabs just cant deal with LP 5.0 Too much hassle and effort to put into a almost 3 year old Tablet, IMO Anyways, thats my rant.
