Hi,

after converting some containers to ploop, I noticed the following errors in dmesg:

....

...

Other containers work w/o any issues. I tried upgrading kernel to latest stable 2.6.32-042stab078.27, which didn't help at all. Centos 6.4 64bit.

If I mount the ploop file and fsck it, no errors are found.

Disks seem fine nad no problems otherwise with them.
