Out of curiosity, I never got MCE on my system at home (last kernel
before one below was 2.6.0-test2, and it did not complain for
different kernels at least since November 2001), yet after recent MCE
changes I got during fsck:

MCE: The hardware reports a non fatal, correctable incident occurred on CPU 0.
Bank 0: f65980000000baff

System booted these 2.4.x kernels which are supposed to contain
off by one fix, without complaints (first number = no. of boots):

8 Linux version 2.4.20-30 (root@ppc) (gcc version 3.3 (Debian))
1 Linux version 2.4.20-4GB-athlon (root@Athlon.suse.de) (gcc version 3.3 20030226 (prerelease) (SuSE Linux))

2 Linux version 2.4.21-0.11mdksecure (quintela@bi.mandrakesoft.com) (gcc version 3.2.2 (Mandrake Linux 9.1 3.2.2-2mdk))
2 Linux version 2.4.21-0.13mdk (quintela@bi.mandrakesoft.com) (gcc version 3.2.2 (Mandrake Linux 9.1 3.2.2-3mdk))
4 Linux version 2.4.21-pre7 (root@ppc) (gcc version 3.2.3 20030331 (Debian prerelease))

Any idea what's going wrong?
