Bug#596449: linux-image-2.6.32-bpo.5-openvz-amd64: kernel BUG/OOPS
Version: 2.6.32-21
Hi again.
I booted into the latest linux-image-2.6.32-5-openvz-amd64 from squeeze,
and I still see this issue. This time it was triggered by trying to
view a Wordpress site hosted in one of the VE's. I don't know's with
these PHP apps...
I tried to retitle my bug as I'm not so sure it's SHM related any more,
and evidently the problem isn't confined to the -bpo package from
Backports, either. I'd appreciate if a maintainer could make the
appropriate change for me. And possibly mark this as present in
2.6.32-21 if necessary. Thanks.
For the time being I'm reverting to 2.6.26-2-openvz-amd64 on this
machine (as it's sort of a production server). I've never had this
issue in that kernel version.
