    well, take a look at: http://www.osdl.org/archive/dmo/DAC960/

    I use that driver for some months now w/o any problems at all where 2.4.11
    driver version has some problems. I use these controllers:

    - Mylex DAC1164P PCI RAID Controller, 64MB cache
    - Mylex DAC960PTL1 PCI RAID Controller, 8MB cache

    hmm, never saw those messages. Already fsck -f'ed? Anyway, those messages
    would scare me :)
