Hi,
during the holidays i tried to reactivate my old fax card,
but i get a kind of oops in the system log. Fax is received, so
is this really something to worry about?
(cpuinfo, lspci is attached)
Kind Regards
Dietmar

this is an mdelay(2) (or more depending on ioctls) in irq context...
that's naughty and nasty for latencies and potentially for time
keeping..
(but it's not an "immediate crash" kind of thing, just really sloppy/bad
code)
