It's always around 4.68 seconds and happened 7 times in the last 12 hours. A simple calculation (2 ^ ACPI_PM_MASK / PMTMR_TICKS_PER_SEC = 2 ^ 24 / 3579545 = 4.686968875) shows: There is almost exactly one pmtmr-cycle missing. Could this be caused by a pmtmr-wrap when the system is in a sleep state? -jo -- -rw-r--r-- 1 jo users 62 2007-04-29 22:29 /home/jo/.signature
