Re: [linux-audio-dev] VP kernels

Hi, Sure. I've been testing 2.6.9-rc1-mm1-S3 SMP on a P4 HT SUSE 9.1 Pro box. In fact I've been struggling with the VP's ever since O3, while on SMP/HT. It hasn't been a pleasent experience, to say the least. My latest findings, S3 inclusive, goes something like this: - can only have it stable or even bootable if CONFIG_SCHED_SMT is not set. - systematic hardlocks when jackd -R is started while on softirq-preempt=1 and/or hardirq-preempt=1. - can't get to burn CD/DVDs at all, even with that scsi_ioctl.c command verification bypass. - can only pray while having the boot/init process reach the xdm login prompt successfully. More times than I find fair and enough, it simply dies on the beach, so to speak. And to make things worst, right after when this happens, some hardware components start behaving erratically. Only a (very) cold boot (i.e. extreme power down) seems to be the solution to this strange side-effect(s). OTOH just by rebooting on a stable vanilla kernel ends all this crappy annoyances ;) This all gets me feeling about the edge being fed up with this VP thing, even more when, quite ironically, this machine works fine let alone with a 2.6 vanilla SMP/HT preemptible kernel. Yeah, no xruns while running jackd -R -p 128 -n 2 ... (jack-0.99.0) Just some late-night thoughts... and please forgive me for being on the negative side this time ;) Gotta get to sleep now... -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org
