Hi List,
I upgraded one of my boxes from 2.6.15 / 0.7.15 to 2.6.20 / 0.7.23 - I
use the patches http://linux-vserver.org/ for para-virtualized guests
anf mount the drbd disks inside these guests.
Worked fine the last year, now after the update I get kernel oopes when
I try to send the device to secondary state - the whole mount operation
is executed in the virtual context of the guest - running it on the root
host works fine.
It forces me to do a reboot -nf because ecach normal reboot will freeze
on "sync".
The output of the oops is below,
any hints on this ??
