Hello,
I'm a new user of Fedora 12 CCRMA and am quite impresssed - thanks for
the great overlay. I've come from a few years of Ubuntu and am trying
to settle into a more dedicated audio workstation setup. Anyway -
this may be more of a general linux question, but do you know why I
occasionally get these in the dmesg log:
hpet1: lost 2 rtc interrupts
hpet1: lost 4 rtc interrupts
hpet1: lost 3 rtc interrupts
hpet1: lost 3 rtc interrupts
hpet1: lost 2 rtc interrupts
hpet1: lost 3 rtc interrupts
hpet1: lost 2 rtc interrupts
For example, these were in the dmesg log after playing with Muse
yesterday. I think I have seen these before with Rosegarden and on
Ubuntu also in the past. I've set the rtc clock like this...
chmod 666 /dev/rtc0
echo 1024 >/sys/class/rtc/rtc0/max_user_freq
Qjackctl/Jackd was running and everything else seemed smooth. The
system is 32bit Fedora 12 w CCRMA realtime kernel
(2.6.31.12-1.rt20.1.fc12.ccrma.i686.rt). Big hard drives and 2GB
memory. akmod to build the nvidia drivers. M2496 audio and a variety
of other things...
It has been suggested that this could be a motherboard issue not being
able to provide accurate timing? Any other ideas? Suggestions?
Thanks, Geoff
