Hi !

I still have panics, after mounting the FreeBSD-2.1 cdrom and doing a
find /cdrom -print 

I think I have the last recent version of kernel (cvs-cur 1770)

Fatal trap 12: page fault while in kernel mode
fault virtual address	= 0xf0e9800f
fault code		= supervisor read, page not present
instruction pointer	= 0x8:0xf0104a6b
code segment		= base 0x0, limit 0x\M^?\^Aype 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor eflags	= interrupt enabled, resume, IOPL = 0
current process		= 182 (find)
interrupt mask		= 
panic: page fault
