I seriously demand that this be changed into "RTC broekn under..."! :) >> BTW, other than MPLayer problems, everything else works great. BTW2, 2.6.15 has an option in ALSA to use RTC as timing source (CONFIG_SND_RTCTIMER). I do not have it activated ATM, nor do I use it (as said, I used "-ao null" for mplayer), but would use of alsa with this rtc timesourcing also crash? >Bradley and Jan, try the below patch and see if it doesn't deadlock the >system. I'm not sure why they pulled out the mod_timer add_timer and >del_timer from the rtc_lock, but there might be a call back to it. Well, it did not deadlock my system. Interesting! It displayed "BUG", as posted multiple times here. Otherwise, it just oopsed. That is, I could continue using the system, with the exception, of course, /dev/rtc. Opening rtc however did not lock a process trying to do so, but instead (as designed in the code) returns -EBUSY. > >Index: linux-2.6.15-rc7-rt1/drivers/char/rtc.c This patch fixes the rtc BUG for me.
