Unable to boot

System: Kubuntu (adm64) 14.10.
Last update: 4-Jan-2015
No proprietary drivers.
No 3rd party software.

The last kernel I was able to run on my Utopic system is 3.16.0-17-generic. Every update thereafter failed. The last one I tried is -28.

- I've tried regenerating /boot/grub/grub.cfg but there are no differences with previous file.
- The kernel command line is the same for both kernels.

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1407505

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[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 v3.19 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.

[Philippe Clérié (pclerie)]

Tried v3.19-rc2-vivid as requested. It failed in the same manner. No change.

[Joseph Salisbury (jsalisbury)]

I'd like to perform a bisect to figure out what commit caused this regression. We need to identify the earliest kernel where the issue started happening as well as the latest kernel that did not have this issue.

Can you test the following kernels and post back? We are looking for the first kernel version that exhibits this bug:

v3.16.3: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16.3-utopic/
v3.16.4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16.4-utopic/
v3.16.5: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16.5-utopic/

You don't have to test every kernel, just up until the kernel that first has this bug.

Thanks in advance!

[Philippe Clérié (pclerie)]

Looks like 3.16.4 is your baby.

Thanks for the speed! :-)

[Joseph Salisbury (jsalisbury)]

I see the CONFIG_DRM_RADEON_UMS kernel option was disabled in Utopic but not Trusty. However, you did not see the bug until after 3.16.0-17, but CONFIG_DRM_RADEON_UMS was also not set in 3.16.0-17.

I think our best bet is to bisect between v3.16.3 and v3.16.4. It will require testing about 8 - 10 kernels. I'll build the first test kernel and post a link to it shortly.

[Philippe Clérié (pclerie)]

The only thing I hate more than bugs is reporting them. :-)

OK! You build, I test.

But give me more than one kernel at a time.

Philippe

[Joseph Salisbury (jsalisbury)]

I started a kernel bisect between v3.16.3 and v3.16.4. The kernel bisect will require testing of about 7-10 test kernels.

I built the first test kernel, up to the following commit:
be35ff0f45bf85f0390b3fda3c6df6fc55fa4117

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1407505

Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

Thanks in advance

[Philippe Clérié (pclerie)]

OK! I'll check that one out this evening.

I don't know what the constraints are, but if you must build kernels based on my tests, then this is going to take a few days.

On the other hand, if I have a bunch of kernels, I can install them all at once, boot one then boot the next until we find the culprit. That's at most one hour, not counting download time, which for me would be around 15-30 min per kernel, but that can be automated.

Whatever the method, as I said, you build them, I test them.

[Philippe Clérié (pclerie)]

First kernel fails!

[Philippe Clérié (pclerie)]

Side note:

I have been getting an error at boot since Trusty:

Error: Diskfilter writes are not supported.

I work around it by doing something else while the thing boots. Anyway, I don't get that error with the kernel builds you had me testing.

[Joseph Salisbury (jsalisbury)]

Unfortunately we can't build more that one kernel at a time during a bisect. The bisect needs to be told whether the last kernel was 'good' or 'bad', so it knows what commit to build up to next.

I built the first test kernel, up to the following commit:
907ed7ee43a3fee9759f99f163fe34754e49a006

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1407505

Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

Thanks in advance

[Philippe Clérié (pclerie)]

Second kernel fails.

[Joseph Salisbury (jsalisbury)]

I built the next test kernel, up to the following commit:
1423ca3aa4335d5443dc4919ee089689750501cc

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1407505

Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

Thanks in advance

[Philippe Clérié (pclerie)]

Third kernel fails.

[Joseph Salisbury (jsalisbury)]

I built the next test kernel, up to the following commit:
d528dcb9cac01b5ced231134e1efc7e88b4d9b20

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1407505

Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

[Philippe Clérié (pclerie)]

Fourth kernel fails.

[Joseph Salisbury (jsalisbury)]

I built the next test kernel, up to the following commit:
fc065a4cecb9d4936afc5d1d083c061a56dc37b4

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1407505

Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

[Philippe Clérié (pclerie)]

Kernel #5 works. :-)

[Joseph Salisbury (jsalisbury)]

I built the next test kernel, up to the following commit:
d5a1560b20bff6a1afadd68934617d630732b5d5

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1407505

Can you test that kernel and report back if it has the bug or not? I will build the next test kernel based on your test results.

[Philippe Clérié (pclerie)]

Kernel #6 works.

[Philippe Clérié (pclerie)]

Anything new?

I'm was running: "apport-collect 1407505", all of my comments up there are autogenerated by apport-collect, I'm sorry for the quantities.
I have updated from Ubuntu 15.10 to Ubuntu 16.04 LTS and now I'm affected from this bug.

The kernel version is: 4.4.0-21-generic
Running: dmesg | egrep 'drm|radeon' I'm getting this error:

[Marco Graziotti (graziottimarco)]

It's necessary to open a new bug report?

Because this report it's for Ubuntu Utopic (no longer supported) and Ubuntu Vivid (that it's supported yet).

[Cgiraud (cgiraud)]

Xenial also impacted.

[penalvch (penalvch)]

Philippe Clérié, given the originally reported issue was resolved when you upgraded from Utopic to WIly, this report is considered closed.

For any new issue afterwards, please file a new report.

Thank you for your understanding.
