    I upgraded one of my main servers to the Tyan S2882 and Opteron 246's
    a few months back. Since then, I have noticed semi-random system
    lockups running Red Hat Enterprise Linux WS release 3 (Taroon Update
    3) with the 2.4.21-20.ELsmp kernel. The lockups seem to occur around
    the time of high file system IO ie) backups / tar's / etc. The
    symptoms are -- I can ping the machine, I can even portscan the
    machine and see the active tcp ports -- but, I can't ssh (or anything
    else into the machine) and the console is completely locked. The
    machine "was" running an Adaptec SCSI PCI-X card out the back until I
    thought the problem to be that... since then I have removed the card
    and replaced the RAID which it ran with two internal SATA 400 gig
    drives (sata_sil). The lockups still happen with high IO on the
    filesystem. Strange thing is, I get NOTHING in syslog!!! Nothing at
    all. In fact, when I hard-power-cycle the machine when hung, after
    the machine is up and I run `last`, I see the reboot I did. Its like
    the machine is in some funky psuedo up state... I've tried new memory
    with no success either.

    I'm pulling my hair out at this point trying to figure out my next
    step. Any help or ideas would be great.

    Try a current kernel. Especially SATA support is pretty sparse
    in its error reporting in older kernels. 2.4.21 is almost historic
    by now.

    If you are lucky the problem goes away. if you are less lucky you
    at least get an error message.

    At one point when the SCSI was still in the machine I did try
    something in the 2.6 kernel range with the same lock ups. I will try
    again with SATA. Any version recommendations?
