Comment # 14 on bug 1206766 from Takashi Iwai

OK, then could you boot with snd_usb_audio.dyndbg=+p option, and get the dmesg
output with the working state?

I'm building yet another KMP in OBS home:tiwai:bsc1206766-kmp2 repo, the same
usb-audio-kmp-default.  It's based on 6.1.x but with a few more fixes and a
patch revert.  Let's see whether this works.

Uninstall the previous usb-audio-kmp-default, and install the new one from
*-kmp2 repo.  Then retest with it.  If it doesn't work, please get the kernel
log with snd_usb_audio.dyndbg=+p boot option again for the broken state, too.
