2.6.17.
Basically - playing sound with
mplayer -ao alsa:device=hw=1 or whatever - and then unplugging the
soundcard completely wedges lsusb/usb configuration, until the mplayer
process is killed.
cat /proc/bus/usb/devices stalls.
Please get the machine into the wedged state, then do
dmesg -c
echo t > /proc/sysrq-trigger
dmesg -s 1000000 > foo
then send foo, thanks.
