--bg08WKrSYDhXBjb5 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Hi Jeremy: Thanks for your detailed response. Here are the answers I have thus far: On Sep 16, Jeremy Chadwick wrote: > acd0 is a CD/DVD drive. ad4 is a hard disk. What exactly were you > doing with the system at the time these errors appeared?

I was not at the system at the time. I never have had a disk in the drive nor is /cdrom mounted currently. I have dump backups that run in the middle of the night on the various filesystems. > Can you please provide full details of what these disks are connected > to? I'd like to see dmesg output for ata0, ata2, and ata3, as well as > the atapci devices those ataX devices are attached to, ditto with > vmstat -i output.

I'll take a look at this page.
