ok, another thing i noticed:
your "cat /proc/driver/rtc" gives
...
update_IRQ : no
periodic_IRQ : no
my configuration says:
periodic_IRQ : yes
Maybe you should disable HPET in your kernel. As far as i know nobody
is using it. Especially the kernel option "HPET Control RTC IRQ"
may disable your /dev/rtc.
/Werner
Now I disabled all options I found that contained the word HPET:
CONFIG_HPET_TIMER=n
CONFIG_HPET=n
CONFIG_HPET_MMAP=n
I also followed Martin Habets suggestion and set
CONFIG_RTC=y
CONFIG_GEN_RTC=n
and also
CONFIG_SND_RTCTIMER=m
to
CONFIG_SND_RTCTIMER=y
Without success.
-----------------------------------
Then I built a new kernel (2.6.15.1) (previos was 2.6.13)
Now the timer is working, but my usb card isn't anymore, while the pci
card is working.
jackd started with PCI-card (hw:0): (OK)
