Hello,

I have a similar problem with the latest kernel.

Restarting openvz vps server hangs and only a mount is active, after that nothing works to stop or unmount that vps. Only reboot node fixes the problem.
When i boot with previous kernel restart or stop/start works great.

I discovered this problem when i was running a script to find certain files and change ownership and saw that i had memory allocation errors.

SLUB: Unable to allocate memory on node -1
cache: ext4_inode_cache, object size: 1056, buffer size: 1064, default order: 3, min order: 0
node 0: slabs: 4466, objs: 132900, free: 0
node 1: slabs: 1760, objs: 51477, free: 0

With both the latest kernel and the previous i get those errors.
Memory itself is ok.

CT-965 /# free -m
total used free shared buff/cache available
Mem: 6144 368 4680 29 1095 5388
Swap: 1024 0 1024
