	tested:

	Indy IRIX 6.2, NFS server HPUX 9, autofs on Indy
	ftp:/pub on /hosts/ftp/pub type nfs (nosuid,nodev,vers=2,dev=180000)
	=> PANIC

	Same Indy, xfs at NFS server Indigo 2, mounted with mount(1M)
	(vers=3,rw,nosuid,quota,soft,dev=140003)
	=> works as supposed.

	Same Indy, xfs at NFS server Indigo 2, mounted with mount(1M) -o vers=2
	(vers=2,rw,dev=180000)
	=> PANIC

	Indigo 2, IRIX 6.2, xfs at NFS server Challenge L
	autofs: (nosuid,nodev,vers=2,dev=180007)
	=> PANIC

	All of them have:

	Patch SG0002284: XFS rollup #9 for 6.2
	Patch SG0002253: ONC3 6.2 AutoFS Rollup for BDS
	Patch SG0002187: 6.2 all platform kernel rollup
	Patch SG0002147: Automount command rollup for IRIX 6.2
	Patch SG0002143: Mount command rollup for 6.2
	Patch SG0002104: NFS rollup #8 for Irix 6.2

	and others...

	Analysis:

	<0>PANIC: KERNEL FAULT
	PC: 0x8819e99c ep: 0xffffcc08
	EXC code:128, `Software detected SEGV '
	Bad addr: 0x0, cause: 0x8<CE=0,EXC=RMISS>
	sr: 0xff03<IM8,IM7,IM6,IM5,IM4,IM3,IM2,IM1,IPL=0,MODE=KERNEL,EXL,IE>
	...
	CPU 0 was in kernel mode running the command 'ustat-panic'

	Same systems, w/o those patches, doesn't panic:

	Patch SG0002042: NFS rollup #7 for Irix 6.2
	Patch SG0001907: XFS rollup #8 for 6.2
	Patch SG0001717: All platform kernel rollup patch


	Mi guess: Patch SG0002104 breaks nfs 2

	Comercial software afected: Softimage 3.5 :-(
