I see something strange that may be related to these issues. When I turn off
my box and turn it on again after a couple of hours, and run Linux, the clock
is apparently late, although it shows the right time in the CMOS setup right
before booting the kernel. The amount of time the clock is late (in Linux)
depends on how much time the box has been off (it increases about 4 min. for
each hour, so the clock is about 30 min. late if the box has been off for 8

This has been present on all kernels since 2.6.8 at least (I did not run
earlier kernels on this box), but I haven't tried 2.6.10-rc3-mm1 yet.

Me too. ;-)
