Hello,

I started to have problems with the kernel 2.6.26 since the rt13 patch:
when I start the JACK server, I can't launch a synthesizer application such as minicomputer without experiencing a freeze about 10 second after having launched it. I have to shut down my computer, then reboot. I tried with a higher buffer size (4), and the only difference was the time it took to freeze again.

I also wanted to ask why the patch you gave at the beginning of january, to make alsa_seq work, hasn't been applied to the official RT kernel, even to the GIT one, because I systematically have to use it each time I compile a new version of the RT patch.

Thanks.

It's in 2.6.26.8-rt14. Looks like it got lost in the shuffle for a bit.

Indeed. My mistake.

But the freezes are still here.
I don't know if it can be of any help, but here's what I get with dmesg before:

Real Time Clock Driver v1.12ac
rtc: lost 13 interrupts
rtc: lost 10 interrupts
CE: hpet increasing min_delta_ns to 15000 nsec
rtc: lost 8 interrupts
rtc: lost 18 interrupts
CE: hpet increasing min_delta_ns to 22500 nsec

Those lines get erased when I restart the computer.
