The message repeats 4 times in 0 seconds (wow!), waits 8 seconds, and repeates again twice.  Then, system becomes unstable and it is necessary to use the magic sys-rq key to recover.  Recently, this happened, i rebooted, and it happened right off the bat again! (which leads me to believe it *may* be a cooling problem, but it probably isn't).

trying 

   Option "NvAGP"  "1"

 in my XF86Config file.  I'll keep you posted on how it works (hopefully, i'll get my screensavers back)

[Comment 3 Donnie Berkholz (RETIRED) 2004-02-01 22:44:13 UTC]

Could you please test newer drivers (1.0.5336-r1 in particular, since that's latest)?

[Comment 4 red0x 2004-02-21 14:34:46 UTC]

the NvAGP option has not helped, I just emerged the most recent drivers today, so we will see how that goes.  Also, I have upgraded to 2.6.3-gentoo-r1.  Wish me luck!

[Comment 5 red0x 2004-02-28 05:27:34 UTC]

Unfortunately, I'm still getting such errors with the new drivers..  :(

[Comment 6 red0x 2004-03-08 00:03:00 UTC]

upgraded to 2.6.4-rc1-mm2
I think this may have been a part of the mremap bug...  not sure.  I figured it was worth a shot.

Other things changed: More cooling, removed extra hard drive, tried a PCI promise IDE controller (did not help), new thermal goo and heatsink on processor.

[Comment 7 red0x 2004-03-16 08:58:14 UTC]

It seems that my upgrade to 2.6.4-rc1 has fixed all my problems with the video card.  If I have anymore troubles, I'll reopen this bad boy.
