    SubjectRe: [BUG] 2.4 series: IDE driver
    Date
    I own an HP Pavilion ze4145 notebook, and the ALi5x3 chipset bombs after about 
    30-40mins of use with "hda: lost interrupt" commands, and this continues
    until I cut the power, though sometimes after about an hour it will reset and
    go on, but it is very iffy. I noticed that "32-bit I/O" was disabled by
    default in the BIOS, however I have enabled it. Is this a problem in the
    kernels ALi drivers or what? The XP install that came with it works fine.
    What suggestions to fixing this? Thanks
