Hi,
After upgrading to Kernel v 2.6.24 hwclock does not work anymore because it times out while waiting for /dev/rtc to give a tick.
/dev/rtc exists.
It only works with the option --directisa.
However it did not show this behaviour on (debian package ) kernel v 2.6.22 and earlier.
My PC is a ACER Aspire 1694WLMI Laptop.
Jackflash:/# hwclock --show
select() to /dev/rtc to wait for clock tick timed out
Jackflash:/# hwclock --show --debug
hwclock from util-linux-ng 2.13.1
Using /dev interface to clock.

Hardware clock is on local time
Assuming hardware clock is kept in local time.
