Has anyone learned anything more about the drbd file corruption issues? It 
has started to become a big problem now. I have two different servers, 
different motherboards, both running scsi disks on an md0 device. I'm 
getting them both to go read-only. About every couple of days (and sometime 
multiple times a day) I'm getting this error.

I'm using drbd version 0.7.17 on both. Might there be a fix in a later release?
