I have a laptop that shares interrupt between ath0 and snd_hda0 devices.
Machine works under the RELENG_6 normally. Now, on the RELENG_7 (and
CURRENT), attempt to ifconfig ath0 up usualy hangs the machine in the
next 2-5 minutes.
Hang is hard, I even cannot switch the console to look at the kernel
messages or enter the ddb. Also, laptop does not have a serial port.
Not setting the ath0 up, or, unloading snd_hda.ko before activating
the interface, allows machine to work. Wireless works without problem,
interrupt rate is as expected.
Any advice ?
