Yes, the patch doesn't eliminate these errors; it merely does something
more intelligent with the error code than "Sit around and wait for

like it's doing the right thing. However, it'd be useful to have
timestamps on the printks to know for sure.

Hrm, you might want to update your disks to the latest firmware levels
(B51C)... be wary that the firmware updates occasionally nuke everything
on the drive. :(
