hi andrew!

I'm sorry, but it's not fixed in current 2.6.13-rc3-mm3. I did an emerge mono
right now to test it, and I got this one:
Jul 29 15:26:37 [kernel] note: mono[11138] exited with preempt_count 1
Jul 29 15:26:50 [kernel] file[14627]: segfault at 00002aaaab453000 rip

00002aaaaaf652cf rsp 00007fffff905f80 error 4

DEBUG_KERNEL/ PREEMPT/ SPINLOCK are enabled, but I didn't get more info about
the bug. Did I forget any debug option?

greets,
