    >From the previous posts and replies, one fix or workaround is to reassign your
    soundcards IRQ and re-boot, it worked for me on the first reassignment, my code
    also was from the 28th, code right after the 2nd Arp patch notice. If the cvsup
    worked let us know.

    Here's some of the notes from the other thread:

    I had the same problem where my kernel would lock up until I changed the
    soundcard PCI slot -- as well as my network card -- and assigned irqs to each
    of those slots and my video card. This appears to be because of irq
    conflicts. Here's what I found this in the LINT file:

    # Note: It has been reported that ISA DMA with the SoundBlaster will
    # lock up the machine (PR docs/5358). If this happens to you,
    # turning off USWC write posting in your machine's BIOS may fix
    # the problem.
