Package: linux-image-amd64
Version: linux-image-3.16.0-8-amd64
Severity: important

Dear Maintainer,

here we go again, i hope this time we get a bug nummer for this report :)

after upgrading to the latest linux-image-adm64 on jessie we're experiencing several issues which led us
to downgrade to linux-image-3.16.0-7-amd64 again and deinstall linux-image-3.16.0-8-amd64. It's happened
until now on a COROSYNC/DRBD Cluster where standby node has been upgraded and after the upgrade the system
froze, see [1].

On another MySQL-Slave where we applied this kernel - the system - after running some time rebooted due to
a kernel panic. I wasn't fast enough to catch the kernel panic on the screen as VMware HA-features instantly
rebooted the system. Both systems run in a VMware HA-Cluster on different ESXi runhosts.

So for me, linux-image-3.16.0-8-amd64 smells fishy and i was wondering if there are other users which have
problems?

Cheers,
Werner
