Where are the lowlat and preempt patches for 2.4.20?
Not on the net at this point. I have been hand tweaking the originals to
patch cleanly (trying to fix the failing chunks).
Ah, i see.

I've tried every kernel from 2.4.20-pre5 up to 2.4.20-pre10, and again
2.4.20-pre10-ac3, which caused a lockup on my system in the past, this
afternoon. And I couldn't reproduce even _one_ lockup. I use another IDE
interface though: a cmd649 add-on controller. The lockups happened with
the onboard IDE interface (VIA KT333 chipset, vt8235 southbridge).
To add one more datapoint to the thread and (apparently good news): I'm
testing 2.4.20 (final) + lowlat + preempt + acpi + alsa + jack and the
computer seems to be chugging along nicely. This is with today's alsa. A
slighly older alsa did lock the computer after 5 or so minutes of jack
activity but I managed to reboot it with the sysrq magic key. With the
newest alsa I got jack + freqtweak + ams (with the demo patch) running
for 50 minutes until for some reason jack died due to a watchdog
interrupt. Not bad. I can email them to
you, use at your own risk :-)
no. no need for that. i'm not so brave. :)
BTW, results in my current tests are inconclusive, a couple of times I
managed to freeze the machine soon after I started just jackd and
qjackconnect. I'm currently trying to see if I can stat the stuff from
the text console so that I can try to catch some register dumps through
the sysrq magic key...
Thanks for your efforts.
