usb-audio - kernel oops 2.5.72

usb-audio - kernel oops 2.5.72

[cliffw]

Am attempting to get linux-2.5.72 + snd-usb-audio happening.
Results have been poor. Machine is VIA C3, ALSA + jack working 
fine with the built-in via audio. Tried various kernels, 
real ugly failures with 2.5.70, also have tried 2.5.72-mm2. 

So far, this is the best I can do:

JACK compiled with System V SHM support
loading driver ..
creating alsa driver ... usb-audio|1024|3|44100|swmon|swmeter|soft-mode
open
Rectangular dithering at 16 bits
port alsa_pcm:capture_1 has mixdown = 0x40017e70
port alsa_pcm:capture_2 has mixdown = 0x40017e70
port alsa_pcm:playback_1 has mixdown = 0x40017e70
port alsa_pcm:playback_2 has mixdown = 0x40017e70
starting engine
ALSA lib pcm_hw.c:494:(snd_pcm_hw_start) SNDRV_PCM_IOCTL_START failed: Broken

i fixed a bug in usb-audio driver on the cvs now.
there are some calls of functions which may call schedule() in the
spinlock.

please try the cvs version.


ciao,

you don't need alsa-driver tree to compile the ALSA on 2.5.x (unless
you use the drivers in it).  the codes in alsa-kernel tree are ready
for 2.5 kernel.  that is, copy the files and directories to 2.5 tree
and build the modules there.

it would be nice to have a simple sync script for that...

Well, if you want simple, i can do that :)
This appears to be working for me....(i wait for the compile, again)

if [ ! $1 ]; then
        echo "Need arg for destination directory"
        exit 1
        fi

if [ -e $1 ]; then
        DEST=$1
else
        echo "Destination $1 doesn't appear to exist"
        exit 1
fi

HERE=`pwd`
BASE=`basename $HERE`
echo $HERE $BASE
if [ $BASE != "alsa-kernel" ]; then
        echo "Must execute me inside alsa-kernel!"
        exit 1
        fi

echo "Copying alsa-kernel cvs to $DEST"

# I could be really cute here and copy globs, but
# That Would Not Be Safe

CVS version does not throw the oops, but the device still fails. 
2.5.73 stock still has the oops. 
2.5.73 + cvs does not throw the oops, but the devices
i've tried are still not connecting properly.
Appears to be an issue at usb_submit_urb(), but i'm not deep 
enough to figure it out.
Will gladly furnish more data upon request, or test patches.
Please advise.
