    I have been wondering about HPT37x in Fedora Core (development) kernel
    called kernel-smp-2.6.7-1.501.i686. It doesn't find one of the cards
    attached to a HPT372A card that I have.

    I tried also to boot with a bit older kernels: 2.6.3, 2.6.5 do work just
    fine (except of 2.6.5 barfs the keyboard..).

    I tried also with 2.6.7-1.494smp (FC devel kernels), and that too
    does fail. I think I had also some a bit older 2.6.7, also that
    one failed. I didn't get around to try any 2.6.6 kernels.

    Any ideas ? Will this patch help ?
