Subject: Linux 2.6.21: pmtmr losing time
Date: Mon, 30 Apr 2007 14:52:00 +0200	[thread overview]
Message-ID: <20070430125200.GA5379@sommrey.de> (raw)

Hi all,

after switching to 2.6.21 the system clock sporadically loses time on my
box (i386, Athlon MP).
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?
