Bug Description

Several issues have been discovered while testing the ahci-xgene driver. These include failures to discover certain disk types (SSDs), failure to discover disks on certain platforms due to phy tunings/timings, and disks disappearing during reboot loop testing.

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

apport-collect 1350087

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.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.16 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.

Also, It would be helpful to run the apport command mentioned in comment #1. That will tell us which kernel this is against.

This bug applies to the trusty, utopic and upstream kernels. Some of the patches are queued for 3.17, some others are still under discussion.

I've sent out a pull request for this branch for trusty which resolves it:

As patches are accepted upstream, I'll do the same for utopic (providing backports to utopic's 3.16).

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
