These are my suggestions: 1) enable 'options PREEMPTION'. This is a MUST. 2) use SCHED_ULE instead of SCHED_4BSD. ULE is pretty stable on me, but I can't guarantee (especially combining with PREEMPTION). It doesn't hurt to give it a try. 3) Apply these patches: http://staff.mybsd.org.my/skywizard/FreeBSD/sound/jroberson_flushbuf_RELENG_5.diff http://staff.mybsd.org.my/skywizard/FreeBSD/sound/snd_RELENG_5_20050825_035.diff -- Ariff Abdullah MyBSD http://www.MyBSD.org.my (IPv6/IPv4) http://staff.MyBSD.org.my (IPv6/IPv4) http://tomoyo.MyBSD.org.my (IPv6/IPv4) _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
