:-D  !!!!!!    Your joking right?

I know at least half a dozen ways to crash
or deadlock linux.  Perhaps some of the
bugs have been fixed in newer kernels
(I generally report them), but like any
OS out there Linux has it holes.  The
LVM bug where a system can be hung with
a mirrored swap LV is just one.  Reported
it for RHEL 4 but I'll bet it's still
in there (it was obvious that RH had no
intention of fixing it).
