Boot hangs with kernel 3.13.0-32 and newer

[Warren]

"Trusty" 14.04.
Ubuntu 3.13.0-35.62-generic 3.13.11.6

Last kernel I could reliably boot was 3.13.0-31, which I have saved a copy of so I can get booted in emergencies. Newer kernels hang part way through the boot process. I boot into grub, I hit return for the default kernel, for a while get blank screen with backlight lit, then backlight goes out, then total hangup. The only way to repair is to hold the power key to force shutdown, then hit it again for another startup attempt. It takes an average of four forced shutdowns and reboot attempts to finally get a good boot. I have reinstalled grub several times -- it's not a grub issue. It seems like a race condition having to do with the video hardware and driver. You probably have that info in the collected data, but the cpu is AMD A10-5750M with video hardware Radeon HD 8650G. I'm using the latest proprietary video driver from fglrx-updates. (The X-org driver has never worked on this machine...). Reverting to the standard fglrx driver (from flgrx) makes no difference.

I hope you can figure this one out. If not I'm soon going to have to just stick with kernel 3.12.0-31. Let me know if there's other info I can provide.

[Brad Figg (brad-figg)]

This change was made by a bot.

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.17 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[0] http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17-rc5-utopic/

[Joseph Salisbury (jsalisbury)]

If this issue still happens with the mainline kernel, we can perform a bisect to identify the commit that introduced this.

[Susan Cragin (susancragin)]

I appear to have the same problem on a new Lubuntu install. Today's Lubuntu Utopic daily build installed correctly and will not boot for me on a new machine. The Trusty installs and runs perfectly, but when I upgrade the system to Utopic, it no longer boots.

[Susan Cragin (susancragin)]

I thought you might want to see another lspci.
This bug is not happening on my old Lenovo X230 tablet, but is present on my brand-new X1 Carbon with faster processor

[Joseph Salisbury (jsalisbury)]

@Susan, do you also have issues with 3.13.0-32 and newer kernels or only the Utopic 3.16 based kernels?

[Susan Cragin (susancragin)]

Apparently, after taking a look, only with the Utopic based kernels.
And funny thing. I installed Utopic (which didn't work) and then Trusty (which did) alongside it, and suddenly when the dual-boot option was present, I could boot into both without a problem. Now I'm really confused.
So my problem is only present when Utopic is the only install.
?????

[Warren (wseverin)]

I installed linux-image-3.17.0-031700rc5-generic_3.17.0-031700rc5.201409151105_amd64.deb several days ago. It failed on the first two boot attempts, but has since had no problems over about a dozen boots. I hesitate to positively declare that this is fixed in upstream kernels, but it looks very promising.

NB. I have been unable to install the corresponding linux-headers due to unresolved dependences that I have not been able to fix. But that's another topic.

[Joseph Salisbury (jsalisbury)]

Can you also give the latest 3.13 upstream stable kernel a test:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13.11.7-trusty/

[Warren (wseverin)]

Joseph, thanks for the tip and link. I Installed linux-image-3.13.11-03131107-generic_3.13.11-03131107.201409181736_amd64.deb, and related headers . Unfortunately the problem persists in that version.

[Joseph Salisbury (jsalisbury)]

@Warren, thats for testiong the 3.13 upstream stable kernel and confirming it still has the bug. Were you able to confirm the latest mainline kernel, mentined in comment #9 did in fact solve the bug. If it did, then we can perform a "Reverse" bisect to identify the commit that fixes this.
