Subject: 2.6.-test10: bad "__might_sleep" in ALSA sound drivers
Date: Mon, 24 Nov 2003 16:02:26 -0800 [thread overview]
Message-ID: <1069718546.2268.9.camel@moria.arnor.net> (raw)
I get this every time I boot 2.6.0-test10. I think this problem has
been around for a while.
Debug: sleeping function called from invalid context at
include/asm/semaphore.h:119
in_atomic():1, irqs_disabled():0
Call Trace:

The system is a P4 with HT, kernel has SMP & preempt enabled.
There are two sound cards. Here are all the snd_ drivers mentioned in
the output of lsmod:
