Hi Ola, Yes I tested this just now to make sure it wasn't related to the patch. I've reproduced the oops with the official build of 2.6.32-5-openvz-amd64 2.6.32-29. After booting, I did the usual 'mount --bind' onto /var/lib/tftpboot on the nfs server and ran 'exportfs -ra'. A system running a squeeze Debian Live image successfully boots pxelinux via TFTP from that directory, but then it tries to mount its nfs root filesystem there and triggers the oops. At some point I'll change the nfs mount so I don't have to use the 'mount --bind', to try to isolate that as the cause, or in case it's something else triggering it. New oops follows. Thanks.
