Hi Leann,
I think that I see three issues on my box:
1. The "cx22702 no longer works"-issue where cx22702_{readreg|writereg} is
failing.
According to the info in another bug this is because a gpio is
mis-configured accidently.
2. snd_pcm_proc_info_read+0x34/0x180 [snd_pcm] to crash with an uninitialized
pointer.
Maybe this happens due to incomplete error handling for 1.?
and finally
3. Locking issue in sound/core/devices.c where a list is destroyed when it is
not locked.
I am of the opinion that 3. is not related to the other two, because the patch
for 3. just solved issue 3 for me.
Problem 1. and 2. do still exist on my system. I have found the time to test
the gpio fix yet.
Frank
