Hi,

[should I post this to fedora-devel instead?]

I'm running 2.6.6-1.435.2.3 on an amanda backup server.  During last 
nights run, I got these[1] messages in my kernel log.

After looking up on google someone else got this because there were too 
many tags being sent to the drive, but the queue depth[3] is set to one 
of this drive[4] on this controller [2].

Any idea what caused this?
