I've seen this panic on 3.0-stable SMP box

Fatal trap 12: page fault while in kernel mode
mp_lock = 00000003; cpuid = 0; lapic.id = 01000000
fault virtual address	= 0x0
fault code		= superwisor write, page not present
instruction pointer	= 0x8:0xf020b0c7
stack pointer		= 0x10:0xfed64bb8
frame pointer		= ox10:0xfed64bdc
code segment		= base 0x0, limit 0xffff, type 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor eflags	= interrupt enabled, resume, IOPL = 0
current process		= 251 (cvs)
interrupt mask		= net tty bio cam  <- SMP: XXX
kernel: type 12 trap, code=0
Stopped at	generic_bzero+oxf:	repe stosl	%es:(%edi)

The machine is double pII 333 MHz on LX mobo with onboard aic7880
and Intel EtherExpress 10/100B Pro + or someth. similar in other
words fxp0, 256Mb RAM. This panic has occured regardless of turning
softupdates on and off, with AHC_ALLOW_MEMIO and without, with both
versions of nfs. The cvs extracts ports collection from nfs mounted
filesystem. Plaing with vfs.ffs.doreallocblks and doasyncfree dosn't
change anything.
