2016-04-20 Thread Kamal Mostafa 
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-
vivid' to 'verification-done-vivid'.

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!

[Kernel-packages] [Bug 1564950] Re: Kernel panic when using CEPHFS (Hammer) /w kernel vivid-lts on Ubuntu 14.04

2016-04-08 Thread Kamal Mostafa 
This fix is still queued and pending, but has not yet been released (as
of 3.19.0-58.x).

In the meantime, here's an updated interim kernel for Ubuntu Vivid
(amd64) for use on affected machines, comprised of 3.19.0-58 plus
1f041a89b4 (ceph: fix request time stamp encoding):

[Kernel-packages] [Bug 1564950] Re: Kernel panic when using CEPHFS (Hammer) /w kernel vivid-lts on Ubuntu 14.04

2016-04-01 Thread Kamal Mostafa 
I've constructed a test kernel for Ubuntu Vivid (amd64), comprised of
3.19.0-56.62 plus 1f041a89b4 (ceph: fix request time stamp encoding).
Please confirm that this test kernel fixes the problem (installing just
the linux-image-3.19...deb should be sufficient):
