Hi Eric,
Here is the dmesg output of the FreeBSD 6.2 virtual machine that has
ghozzy's probe.c patch in place. His patch prevents the kernel from
using the XSTORE instruction that VMware Server doesn't support. Let
me know if you need any other information.
I don't remember if I cc'd the list or not a few days ago when I
emailed ghozzy, but his patch fixed the installation problem I was
having, and I no longer get the instruction fault panic when the root
filesystem is built.
I haven't put the new VM through any strenuous testing yet, but I will
be over the next few weeks, and I'll update the list if the system
crashes again.
Thank you,
Greg
