I think it was more to do with outright lockups using the ext3 code, rather
than xruns. Yes, switching to ext2 is a good way to test if ext3 is at fault
(I did this, and yes it was). I'm using reiserfs as a workaround (I'd prefer
to have any journalling on my larger filesystems than none at all), although
from what I've read reiserfs might be better suited to audio applications
anyway.
