    Guys, here's a (yes I know, fairly vague) error report - I'm just
    beginning to narrow this down. Any suggestions would be greatly
    appreciated.

    Dual opteron (Sun Fire v20z), 2G RAM, untainted x86_64 kernels (no
    preempt or other fancy stuff, just plain and simple K8 NUMA ACPI
    configs);

    Problem with 2.6.11.11: Machine hangs during backup (amanda) - right
    after the estimates are done the box will freeze hard, nothing on
    console.

    Tried 2.6.12-rc6 in the hope that it would at least print out a panic or
    oops for me: Haven't tried the backup yet, but I got the following in
    the logs which I've never seen before:

    gcc[18818]: segfault at 00000000332c8e54 rip 000000005555a0a8 rsp 00000000ffffba4c error 6
    klogd[3116]: segfault at 000000003ef1b373 rip 000000000804a3b3 rsp 00000000ffffbbe0 error 4
    gcc[18857]: segfault at 00000000332c8e54 rip 000000005555a0a8 rsp 00000000ffffbedc error 6
    gcc[19049]: segfault at 00000000332c8e54 rip 000000005555a0a8 rsp 00000000ffffaefc error 6
    gcc[19097]: segfault at 00000000332c8e54 rip 000000005555a0a8 rsp 00000000ffffb1fc error 6
    gcc[19251]: segfault at 00000000332c8e54 rip 000000005555a0a8 rsp 00000000ffffc9dc error 6
    gcc[19272]: segfault at 00000000332c8e54 rip 000000005555a0a8 rsp 00000000ffffb1bc error 6
    gcc[1569]: segfault at 00000000332c8e54 rip 000000005555a0a8 rsp 00000000ffffb56c error 6
    gcc[16458]: segfault at 00000000332c8e54 rip 000000005555a0a8 rsp 00000000ffffc9ac error 6

    So, with 2.6.12-rc6 all of the sudden klogd and gcc starts
    segfaulting...

    No ECC errors or other anormalities reported via the service processor.

    Anything you want me to try? Need more information?
