Public bug reported:
Opening this on behalf of one of my colleagues at Cisco, we're seeing an
issue on our new S-series S3260 server that's causing the kernel to
crash.
If we have an NVMe device inserted into one of two drive slots, we will
see kernel crash only with Ubuntu. With an NVMe drive in the bad slot,
other OS's will work fine. If we move the NVMe drive out of the bad slot
and into the other slot, everything is working fine as expected. We only
see the kernel crash with an NVMe drive in that bad slot when using
Ubuntu. We tested with HGST and Intel NVMe drives and were able to
reproduce the issue with both. HGST reviewed some logs and they don't
believe at this time the issue is with the NVMe drives.
We're hoping someone from Canonical can take a look to understand what
is the difference between the working and failing slot. The data
collection was done with the NVMe drive inserted in the working slot so
we could access the OS.
I had a connection time out when trying to use ubuntu-bug, so I saved
the apport file and will attach to the bug. I have collected the kernel
and syslog as well, but they are ~9GB. I found a call trace in the
kernel log start on Jan 25 06:02:54 and floods the logs afterwards. I
will include the call trace in a separate text file on the attachment.
** Affects: linux (Ubuntu)
Importance: Undecided
Status: Incomplete
** Attachment added: "contains apport, call trace, lspci, uname, version_sig"
