Description Luis Claudio R. Goncalves 2008-08-07 17:31:42 UTC 
Description of problem:

From drivers/clocksource/acpi_pm.c:

u32 pmtmr_ioport __read_mostly;
...

/*
 * Allow an override of the IOPort. Stupid BIOSes do not tell us about
 * the PMTimer, but we might know where it is.
 */
static int __init parse_pmtmr(char *arg)
{
        unsigned long base;
        ...
        base = simple_strtoul(arg, &e, 16);
        ...
        pmtmr_ioport = base;
        ...
}
