G'day

	Last tuesday i've got an oops on dual opteron host
[ 2xopteron 246, 4G ram, LSI 320-2x, 
2.6.12-rc3, Gentoo 2005.0 
mostly heavy loaded but not that time ]

Symptoms: system hangs, no activity, no disk io 
	i couldn't determine exactly whether sysrq works (this is a remote
	system and screen->minicom->serial console rather specific bundle )
	
This is production server, so i could run memtest only last night but
it could finds nothing. 

[ I have tried to adapt debug rmap patch from Hugh Dickins he sent 
in reply to similar report.
( http://marc.theaimsgroup.com/?l=linux-kernel&m=111101533309675&w=2 )
to 2.6.12-rc5 but looks like missed something ( perhaps amd64 specific )
and just got another oops after boot. ]

So, this is an oops on 2.6.12-rc3
