Hi,

I tried to run VMware after the latest changes in the port, to see if it
would now work for me.=20

I got the following panic (vmnet was loaded, aio.ko as well):

Fatal trap 12: page fault while in kernel mode

---Can't read userspace from dump, or kernel process---

This is on FreeBSD 5.2-CURRENT #20: Tue Jan  6 10:38:48 CET 2004. I'm
going to try to update to more recent sources later this day to see if
it helps.

I'd be glad if someone has any advice.
