I am running 4.8-PRERELEASE #19: Wed Feb 26 00:55:01 GMT 2003.

I cannot reproduce my rebooting problem but it seems to happen while 
using my ATEN usb2serial talking to my gps.  It takes about 5 minutes 
and then I just reboot.

I have a sis630 chipset.  I don't know if the following errors are 
directly related or if I am rebooting for some other reason. It looks 
like the clist panic below is realated to cblock_alloc in kern/tty_subr.c.

Sorry I can't be of more help.
