makeoptions DEBUG=-g #Build kernel with gdb(1) debug symbols options INVARIANTS #Enable calls of extra sanity checking options INVARIANT_SUPPORT #Extra sanity checks of internal structures, required by INVARIANTS options WITNESS #Enable checks to detect deadlocks and cycles #options WITNESS_SKIPSPIN #Don't run witness on spinlocks for speed Ok, the problem seems to happen much more reliably now, but still no panic (so no crash dump). However, I did notice that for some reason I had built an SMP kernel. All kernels that I have seen exhibit this pcm driver hang were apparently SMP kernels...I guess that's the default in GENERIC, which I copied and adapted for my kernel config. As my system only has one CPU, I will build a UP kernel and see if that has any effect. Thanks, -brian __________________________________ Do you Yahoo!? Yahoo!
