Hi all,

I know this is for upstream. But 3.16 ist old, so nobody will care and additionally I know that both sound and USB maintainers are reading this list, this is why I come here :-)

My daughters machine got updated to 13.2. She has a "Midiman M-Audio Keystation USB 49" keyboard. I have the following script to use the box as cheap synthesizer: --- #!/bin/sh trap 'killall -9 timidity; pasuspender /bin/true' 0 killall -9 timidity export TIMIDITY_PCM_NAME=sysdefault ( pasuspender -- timidity -Os -A250a -s 44100 -iA -B1,1 )& sleep 2; aconnect 20:0 128:0 sleep 1 echo "Enter zum beenden..." read x killall timidity ---

Plug in keyboard in "boot" mode:

.... on and on, until panic at 20:04 local time.

My daughter took a picture of the second panic (but I don't know how good the quality is and if we can see anything on it)

What did I already try? * update to 3.17.x from Kernel:stable * downgrade to 3.10.x from 13.1

Both show the same "usb_submit_urb: -16" flood. I did not try long enough to panic the box. My daughter suggested that the panic does happen when she starts playing with the special MIDI functions of the keyboard. I don't know if that's true or if the two panics today are just bad luck.

Grepping through the archived syslog seems to suggest that it happened first on March 23 2014, with 13.1 kernel 3.11.10

With 3.11.10, there is only one call trace from [ 135.889057] WARNING: CPU: 3 PID: 1756 at /home/abuild/rpmbuild/BUILD/kernel-desktop-3.11.10/linux-3.11/drivers/usb/core/urb.c:327 usb_submit_urb+0x3a4/0x3c0() [ 135.889061] URB f3f710c0 submitted while active

And the message is slightly different: [ 135.889439] ALSA midi.c:194 usb_submit_urb: -16

Going further back through the logs would suggest this started with 13.1, 12.3 (kernel 3.7) seems to have worked fine. OTOH the MIDI keyboard is only used once in a while, so this might not be true.

Anything more you need from me? (and *please* don't say "git bisect" :-))

This is a code path for the error recovery, so something went already wrong in the USB side, supposedly. In anyway, could you try the patch below? The problem after reboot isn't cured by that, though. It's the hardware issue, somehow it's screwed up. You'd need to do some hard reset.
