    Could you enable ACPI?
    My dual pII still crashes - I have 192 MB ram, so PTE_MASK doesn't
    explain this crash :-(

    The messages were:

    init.c:112 bad pmd c0004300 (0..0c0001e3)
    remap_area_pte: page already exists
    BUG at ioremap.c

    it seems that the first ioremap() [acpi_map_table() in
    arch/i386/kernel/acpi.c] fails.

    Btw, the test for the idle task in panic() looks wrong, what about this
    patch? [untested, and netscape has eaten the spaces]
