	FreeBSD 3.1-RELEASE, i386, ASUS P2B-S motherboard,
	Tulip-based 100/10 Ethernet card, SCSI disk drives

>Description:

	Two kernel panics have occurred so far with page fault
	while in kernel mode.  Based on the stack dump this appears
	to be different than PR kern/10397 which I filed before,
	which has occurred on the same machine.  Since I filed that
	PR, I have changed this machine to be NFS server for a busy
	filesystem.  Presumably the additional processing is now
	causing this different kernel panic.

	Please see this URL for (a) a gdb traceback from a debugging
	kernel, (b) kernel configuration, and (c) dmesg output:

	   http://www.rahul.net/dhesi/freebsd/crash2/

	I need to put this particular machine into production mode
	soon.  If any of the the FreeBSD developers wants more
	information, please contact me right away.  Otherwise I
	will install a different OS on this machine soon.

>How-To-Repeat:

	Occurs spontanously.

>Fix:
	
	None known to me.

 Hi Rahul,
 
 I think it's much more likely that people will look at your reports if
 you're not using a RELEASE, but rather 3.1-STABLE. Are you not in a
 position to track STABLE?
 
 Also, you should know that ropey NFS in FreeBSD is a known issue that is
 being looked at by Matt Dillon and friends. They're working on the
 problem in CURRENT, with backported fixes for STABLE expected when
 they're well tested.
 
 Ciao,
 Sheldon.

 Hi, I am in a position to track STABLE, and will do so soon.  However,
 the specific uses being made of this machine will be transferred to
 another machine running FreeBSD 2.2.8, because I really need a stable
 file server.  So I don't know if I will be able to provide you with the
 same debugging info in the future.
 
 Rahul

 It's a pity you won't have your STABLE machines doing the sort of work
 that triggers the problem you reported.
 
 If you _do_ encounter the same problem on a STABLE box, please submit a
 PR and mail me the PR number you're assigned.
 
 Thanks,
 Sheldon.
