    Subject[2.6.0-mm2] PM timer still has problems
    Hi,
    Booting with clock=pmtmr causes weird problems here (the system
    complains that clock override failed and the bogomips loop produces bogus
    values). Below is the dmesg output as well as /proc/cpuinfo.
    I have CONFIG_X86_LOCAL_APIC=y and CONFIG_X86_PM_TIMER=y.

    I don't really know whether this box (ASUS L3800C, more data at
    http://bugme.osdl.org/show_bug.cgi?id=1185) has a PM timer or not, but even
    if it doesn't, the code should account for that gracefully.
    I'll be happy to provide any additional info.
