Status changed to 'Confirmed' because the bug affects multiple users.

[Brad Figg (brad-figg)]

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

apport-collect 1648388

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)]

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.9 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'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

After update the latest v4.9 kernel ,the issue still exist.

Lo:
1) To clarify https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1648388/comments/4 did you test 4.9-rc8 or 4.9?
2) Could you please boot into the default Ubuntu kernel (not upstream/mainline) and then execute the following command only once, as it will automatically gather debugging information, in a terminal:
apport-collect 1648388

1 )
    I test kernel version is 4.9-rc8

2 )
    Done. The default kernel version is 4.4.0-21-generic

Thanks

[penalvch (penalvch)]

Lo, could you please provide the full computer model as noted on the sticker of the computer itself (not from the Bug Description, or the result of a terminal command)?

[Douglas Haunsperger (dhaunsperger)]

Christopher,
That's a tougher question than you might think. :)

The full system is a rack-scale product developed by Dell's Data Center Solutions division called DSS9000. This is not a generally-available system, but is produced only for hyperscale and other large-volume clients. However, the motherboard used in the system (DSS 9500M) in question is also used in the PowerEdge C6320 product, which is a generally available product.

Canonical has qualified the half-width (DSS 9520) and full-width (DSS 9500) sled options within the DSS 9000 framework on Ubuntu 16.04.

[penalvch (penalvch)]

Lo, to keep this relevant to upstream, one would want to periodically check for, and test the latest mainline kernel (now 4.10-rc3) as it is released.

Could you please advise?

[Lo (cr7)]

Christopher,
I try the latest mainline kernel v4.10-rc3 still found the issue.
Thanks

[penalvch (penalvch)]

Lo, the next step is to fully commit bisect from kernel 3.13 to 4.4 in order to identify the last good kernel commit, followed immediately by the first bad one. This will allow for a more expedited analysis of the root cause of your issue. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions, or providing a commit from a kernel version bisect is not fully commit bisecting.

Also, the kernel release names are irrelevant for the purposes of bisecting.

It is most helpful that after the fix commit (not kernel version) has been identified, you then mark this report Status Confirmed.

Thank you for your help.

[Lo (cr7)]

Christopher,
I try mainline kernel from 3.12 to 3.19 in Ubuntu16.04.
Still found the issue.

Thanks

[Lo (cr7)]

I try install Ubuntu14.04 in RAID1 and update mainline kernel v4.10-rc3.
It reboots successfully without any error.
Thanks

[Joseph Salisbury (jsalisbury)]

@Lo, It sounds like the 4.10-rc3 kernel exhibits the bug on 16.04 but not on 14.04, is that correct? That might indicate the bug outside of the kernel.

Can you test the 4.11-rc1 kernel with 16.04? That kernel can be downloaded from:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.11-rc1/

It might also be worth while to test the current daily iso image from:
Desktop:
http://cdimage.ubuntu.com/daily-live/current/
Server:
http://cdimage.ubuntu.com/ubuntu-server/daily/current/

[Lo (cr7)]

Hi Joseph

The kernel 4.11-rc1 with 16.04 still has the issue.

[Joseph Salisbury (jsalisbury)]

Does the 4.11-rc1 kernel exhibit the bug on 14.04?
