    Hi All,

    during resync of my raid1 partition (md0) my ubuntu 8.10 suddenly freezes, with the following error on the console;

    CPU 0: Machine Check Exception 4 Bank 4: b2000000000000070f0f
    TSC 1c3469a27ae
    This is not a software problem!
    Run through mcelog –ascii to decode and contact your hardware manufacturer
    Kernel panic - not syncing: machine check.

    my setup is;

    md2 : active raid1 sda4[0] sdb4[1]
    47881664 blocks [2/2] [UU]

    md1 : active raid1 sda3[0] sdb3[1]
    97659008 blocks [2/2] [UU]

    md0 : active raid1 sda2[0]
    97659008 blocks [2/1] [U_]

    does anybody know what is happening here? should a fsck on this /dev/sda2 will do anything? any other things i can test?

    thanks in advance
