[Users] Kernel 2.6.18-openvz-13-39.1d1-amd64 oops

Mon Oct 29 13:34:31 EDT 2007

Thorsten,

Alexey Dobriyan told me that you said you found some misprint
in OVZ patch ported to debian.
Is it true? Can you please point to this? Any patch?

to Frank, can you try using 2.6.18-mainstream-OVZ kernel until this
is resolved in Debian branch and thus confirm that it's purely debian-kernel problem?

Thanks,
Kirill
