next in thread | raw e-mail | index | archive | help
I got a kernel panic when trying to run wine on my SMP current system
(cvsup'ped July 21, 2xPpro233 on Providence mb, smp+softupdates).
Could it be the USER_LDT stuff not working with SMP?
I have appended the stack trace, if someone wants more info just ask.

PS Is anyone working on replacing the clone() calls in wine with
something that could work on FreeBSD? I could only find rather
old messages about it via dejanews.
PPS Which of the sysctl vars am I supposed to tweak to turn
the second processor off?
(Note: I had to type 'panic' twice at the debugger prompt to get the dump)
