Well, it's hard to say, because the hardware could be misbehaving, in which case the software may not know what's going on. It might be interesting to see whether fstat(1) sees anything holding the dsp devices. You could also try using vchans, which would (in theory) let you access the hardware from another device node after the first one hangs. Good luck. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
