Re: mplayer and rtc _and_ possible kernel bug of enhanced rtc in 2.4.21-rc3?

The problem is that CONFIG_RTC _does_not_work_ on a powermac.
CONFIG_RTC is for PC-style (more or less) RTC chips. This is one of two
problems here. If you want a working RTC driver, you must use
CONFIG_GEN_RTC or CONFIG_PPC_RTC (CONFIG_PPC_RTC is gone in 2.5,
replaced with CONFIG_GEN_RTC).
The second problem here is that mplayer assumes that if you have
/dev/rtc, it's the PC-style one and 'echo 1024 >
/proc/sys/dev/rtc/max-user-freq' is meaningful. My guess is that
mplayer makes incorrect assumptions when trying to set this (and use the
RTC_PIE_{ON,OFF} sysctls), and thus there is a bug in mplayer.
