I've gotten that exact error with a self-built Gentoo kernel
2.4.26-r11, the error only happened once, and only during P-1 stage 1.
 The machine quite happily runs overnight torture tests, and I just
blew out the fans a few weeks ago, so it's not a hardware issue.

Sorry I can't offer more.

Do you by any chance use the nvidia driver?  I do, and it's
proprietary and thus to my thinking suspect.
