I have installed FreeBSD-6.1 from cdrom yesterday on my machine
a P4 with hyperthreading. It crashed some hours later when
i was accessing the packages cdrom, specifically doing
cd /cdrom/pa<Tab>
This is with the installed kernel, no modification whatsoever.
I don't have the corresponding debugging kernel, so all i have is:
niobe# kgdb /boot/kernel/kernel /var/crash/vmcore.0

I don't suspect a hardware problem since this machine has run FreeBSD-5.3
and 5.4 previously without trouble, there is no overheating, etc.
As for the cdrom, after reboot i have installed the whole KDE plus a lot
of other things from it without problem.
