USB hard drive hangs machine - Linux Setup, Configuration & Administration

I'm running a Compaq ProLiant ML370 with 4 Xeon processors and 2.5 GB of RAM. I loaded it with RedHat 8, but have since compiled a 2.4.23 kernel. USB core and usb-storage are loaded as modules.

    Default USB hard drive hangs machine

    I'm running a Compaq ProLiant ML370 with 4 Xeon processors and 2.5 GB of
    RAM. I loaded it with RedHat 8, but have since compiled a 2.4.23 kernel.
    USB core and usb-storage are loaded as modules.

    The system runs just great - until I plug a Western Digital USB hard
    drive (250 GB capacity) into the machine (formatted as ext3). As soon as
    I start to copy files on to the USB drive, the system hangs up solid.
    There are no error messages in /var/log/messages.

    I'm also using a USB printer with no problem.

    I thought the problem with USB hard drives was supposed to be fixed in
    the 2.4.20 (or thereabouts) kernel. Any ideas why this happens, and if
    there's a workaround for it? This machine is very soon going to become
    our production server, so I obviously don't want to have it hanging me :)

    Assuming you're talking about USB 2.0 and not USB 1.x, I had the same
    problem with that kernel - check my sig for spec. I'm not sure whether the
    problem is SMP related - although with Linux it seems to be the main
    culprit for hard lock-ups.

    My USB 2.0 add-in card uses a VIA6202 controller chip. There are known
    issues with this chip under Linux, even with kernel 2.4.23. I also have a
    USB 2.0/IEEE1394 combo card, also VIA-based, but the USB controller chip is
    a VIA63xx chip - I've not had a chance to test this fully yet.

    Try upgrading to kernel 2.4.23 - this problem seems to have gone away under
    normal cirstances, although it might be worth running a batch job to
    copy files back and forth, see if it locks up.

    Hope this helps,

    My apologies -- I didn't read your post properly, so I didn't realise you
    were already running 2.4.23. You could try going to www.kernel.org and see
    if they have a patch for 2.4.23, or try 2.4.24-pre(something) - maybe the
    problem has been solved.

    Also, it might be worth opening up the machine and seeing what USB
    controller chip it uses - like I said before the VIA6202 is a troublemaker.

    Best,

    It does not work. (kernel 2.4.18)

    No prob! I'll give that a shot.
     

    Well, lspci says:
    00:0f.2 USB Controller: ServerWorks OSB4/CSB5 USB Controller (rev 05)
    Not sure if that's known to be a problem, but I'll do some research into it.

    Thanks for the suggestions!
