[Bug 1449910] Re: System hangs apparently randomly when disconnecting iScsi volumes
2 nights ago something happened. I have a 5th server which doesn't use
LVM snapshots, but still it's backed up every night. I didn't install
the mainline kernel on this machine, because we thought the problem was
due to snapshots. And it crashed two nights ago, in the same way the
other machines crashed, without using snapshots. It crashed after
finishing the backup. I think the problem lies in the disconnection of
the iscsi volume on which the machines do the backup. On the first
reboot, I had the following in the kernel log:

I don't know if this is related, anyway it happened only on this particular reboot. I now installed the mainline kernel also on this machine.
I changed the title of this bug to reflect the additional information I got.
** Summary changed:

System hangs apparently randomly when disconnecting iScsi volumes

Bug description:
We have several servers here which mount Ubuntu LTS Trusty Tahr 14.04. We use LVM snapshots to do backups during the night. Randomly (witha rate of 1 event every 10-12 days) the LVM snapshot creation runs in some problem. The server hangs and it must be rebooted hardly. No shell, no even any screen output, just a black screen, no ping, nothing. And Magic SysRq key doesn't help.
No logs are written either (I also tried redirect logs to another machine, just in case). This happens with different hardware, and different backup software. The only constant is LVM snapshots. Kernel is 3.13.0-49. We tried the 14.10 kernel (3.16.0-34), we had the same hangs, but this time we had something logged:
