Whoops...
yesterday's version of the sound code had a stupid bug in snd_sync()
which would put your machine in a tight loop with interrupts
disabled... I have fixed it, and updated the distribution, which
is now at the same URL but with a different date & size:
http://www.iet.unipi.it/~luigi/snd970903.tgz
-rw-r--r-- 1 luigi luigi 155747 Sep 4 10:03 snd970903.tgz
(I have chosen not to change name because people tends not to read
followup mails...)
Programs which use the SNDCTL_DSP_SYNC ioctl are affected by the
bug (e.g. timidity). Those with the old code can fetch the new
code or just apply the following patch to /sys/i386/isa/snd/dmabuf.c
