Hi,

Is your processor hyperthreading (and running an smp kernel)? I
remember people having terrible lockups when running jack realtime with
hyperthreading cpus and 2.6.8*. It's quite a bit better (very few
issues so far) on a dual-proc smp machine, but cdburning freezes it
under that kernel.

->Hi,

I have a HP Compaq nx7000 laptop, using Gentoo and vanilla 2.6.8.1
patched with VP (P9) + realtime-lsm patches.
(2.6.8-gentoo-r3 + realtime-lsm, same problem..)

By running jackd -R -d alsa my box freezes (or stops responding).
jackd -d alsa runs ok though. Jack is version 0.98.1 (0.99 also tested),
and no NPTL in glibc. Used alsa driver is intel8x0.

Where would it be best to start troubleshooting..?

Any help would be appreciated. :)
