This is with the latest stable lucid kernel (2.6.32-22-generic
#36-Ubuntu).
I've also tried a mainline kernel (2.6.35-020635rc1) & still get the
same errors except that there's an additional stack trace:

--------------------------------------------------------------------
I've tried booting with "libata.force=noncq" on both kernels (lucid
stable & 2.6.35 mainline) but makes no difference.
I didn't see these errors in Jaunty. I think they started sometime in
Karmic. I upgraded to Lucid in the hopes that the newer release fixed
it but no difference.
I think I've ruled out HDD failure. I get these errors on 2 old (3+
years) Seagate 7200.10 disks as well as a brand new Seagate 7200.12
disk.
There are similar bug reports in launchpad but one difference that I
noticed is that I consistently see the message "failed command: WRITE
DMA EXT" while the other reports fail during a read or some other
command.
I can very reliably reproduce the errors by running a rdiff-backup
'restore' operation from an external USB HDD.
== Steps to reproduce ==
1. Boot into Gnome & login
2. Run 'tail -f /var/log/kern.log' in one terminal window
3. Run 'rdiff-backup --force -r now /media/freeagent/share /share/' in
another terminal
Within a few seconds, I can see the errors show up in the kernel logs.
Running a fast torrent download will do the trick too.
Since I can reproduce the problem so easily, I'll be very willing to
try any special kernel builds to help solve this one.
