Hi Takashi,

Today I finally had some time to try your patches. I have a Terratec Phase 
24FW Card. I did use the latest version (as of today) from 
https://github.com/takaswie/snd-firewire-improve.git on a Debian testing 
system. I did not use dkms but loaded the driver manually:
$ cd sound/firewire
$ modprobe -r snd-firewire-lib
$ insmod ./snd-firewire-lib.ko
$ insmod ./bebob/snd-bebob.ko

First I have to say the driver does work and I can play music through the 
device, so thanks for your work.
Unfortunately I managed to crash my system with it. I was using mplayer2 to 
play sound files and it seems that if I let mplayer2 play multiple files the 
system crashed somewhere between the end of the last file and the start of the 
new file (probably a race or something). I only did some quick testes because 
I hat to reboot after every crash (even sysrq doesn't work anymore), but I 
think the crash doesn't happen every time mplayer2 switches to the next file, 
but most of the time. If I let it play only one file I didn't observe any 
crashes.

Here is the mplayer2 command I did use for testing:
$ mplayer -ao alsa:device=hw=1 <some files>

And here the output of /proc/asound/cardX/#XXX
