Kernel panic - not syncing: CPU context corrupt

[Nylex]

Hi people, I have a new installation of Gentoo and there was no web browser installed, so I did tried to "emerge mozilla-firefox". There were 23 packages to get and I don't know how far it got, but it was doing something to do with GTK when I got this:

CPU 0: Machine Check Exception: 0000000000000004
Bank 4: b200000000040151
Kernel panic - not syncing: CPU context corrupt

There were some syslogd messages, but they just repeated the above. I found another thread saying this problem was due to overclocking, although my machine hasn't been overclocked. The machine didn't seem to be doing much after that, so I just rebooted it.

Hardware: Pentium III 800 MHz, 256 MB RAM, ATI Radeon X700 (I think), Seagate 40 GB hard drive, Toshiba DVD-ROM, 3Com Etherlink XL NIC and some other stuff, but not much.

I'm not sure what I should do, try to "emerge mozilla-firefox" again?

Any help appreciated, thanks.

Run memtest86+

Boot of a current LiveCD and at the prompt type 'memtest86'. Wait for errors.

[Nylex]

I tried that and there weren't any errors :/. Any more ideas?

Thanks again.

It seems to be some hardware issue. Please show dmesg output and say what kernel you have.

Kernel is 2.6.12-gentoo-r6 and dmesg says:

Hi
1) try to do some "hardware debuging" (literally ) - take of CPU cooler clean it from dust, apply new thermal grease, take off RAM clean it's pinned side, reinsert addon cards.

2) try to run mprime ftp://mersenne.org/gimps/mprime2413.tar.gz observe your CPU temp if it fails again although temp isn't too high - bad news propably CPU is broken

[Nylex]

If it was a hardware problem, surely I'd have kernel panic errors and stuff in Slackware too (I dual boot)? I've not had any sort of error like that when I use Slack.

[radoslawc]

Ok, then try to disable [] Machine check exception in procesor type and features. Maybe it's producing wrong output causing kernel panic.
However, I strongly suggest to run mprime for some time (1 h) to check if hardware is ok.
Cheers

[Nylex]

I might try mprime when I have some more time. The other thing you said to do, do you mean I have to recompile the kernel?

Thanks again.

[kueitao]

Sorry for being here too late after asking you to post dmesg output...

Anyway I agree with radoslawc suggestion to disable MCE, but never before being sure you don't have hardware problems.
