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!
