It would be very good to track this down and get it fixed..
hopefully you're able to help a bit and try some things to debug it.

Konrad maybe has some ideas to try..


I would love to track this down and have it fixed or else this is a stopper for majority of us to deploy pvops stable kernel 2.6.32.x in production.  Well at least for me... ...

More related logs and it seems all is related to LVM since all will have the last sysfs file to /dev/block/dm-??/dev... ?
