It's worth pointing out here that a user level application, like ardour,
cannot bring down a system*. Only a system level bug can do that (or
hardware failure). Ardour might tickle the bug, but if your system
crashed or froze while running Ardour then the kernel has a bug.
Possibly, since presumably you've never seen it outside of Ardour (or
you wouldn't be blaming Ardour) it is in the sound card driver you are
using. Jack might also be to blame, since it usually runs with rt
priority, needs special privileges, and seems to interact more closely
with the kernel than most sound servers (I'm guessing--I don't know
where the user/system line is in the alsa/jack stack).
* - Of course, this statement only applies to a system that has memory
protection and preemptive multi-tasking, like Linux, and Mac OS X and
Windows NT+. Old Windows, Mac OS 9 and under, and early microcomputers,
could easily be brought down by a misbehaving application and there was
nothing the OS could do to prevent it.
On the file recovery front, I don't have much advice other than the
usual file recovery standar practice:
Mount the disk read only and back the FS up with dd immediately before
writing anything else to the disk. Attempt to recover the FS /on the
backup/ with fsck (I think Reiser has stable fsck these days).
You might try the ReiserFS support line for some added help (they have a
"$25 gets an answer" page on the namesys.com site, and they might be
worth having on your side during the recover process if the files have
more than $25 value). I reckon $25 is a bargain for presumably
