Subject: kernel 2.6 bug
Date: Thu, 18 Dec 2003 22:26:10 +0100 [thread overview]
Message-ID: <3FE21B72.8090200@esitcom.org> (raw)
hi
I tried the 2.6 kernel today, and have a bug
using snd-usb-audio with the oss emulation I use a gstreamer based
player (I know, I could use alsasink) :D
notes:
* uhci USB
* no modules support (everything in)
* preemptible kernel on
when preemptible is off, I only get the
"cannot submit datapipe for urb <blah>" messages as shown below
restarting the application gives sound again
the application works in 2.4.23 with alsa 1.0.0-rc2
I get the following trace :
bad: scheduling while atomic!
