To my old backup server (running BackupPC), I recently added a PCI SATA card
and 1TB drive, and installed Fedora 13 (and removed 2 IDE smaller drives;
the boot drive is still an older IDE 40G; was running Fedora 11). Messages
log regularly has this set of messages, much more frequent when the backup
is running:

I've googled various words from the messages, but what I find are CD drive
related messages and "now it takes longer to boot, so change modprobe" type
things. I think mine is related to the new drive (just a hint from the "ATA
bus error" and 'ata' all over the messages ;-), possibly harmless messages
or maybe a SATA card config or compatibility problem(?). I'm surprised they
keep repeating - if it was just a config error, I would think it would
adjust once (maybe at boot) and then be done.
Can anyone point me to an RTFM or hints how to research/what is the cause
pretty-please?!
