Hi
I've been having problems getting sound working before (as seen in issue
2072), but I managed to get around that issue, but doing a
load-unload-load of the modules before using them.
But after upgrading to linux kernel 2.6.18 and updating to the latest
version from the hg repository, I cannot get the module to load at all.
I get the following in my logs:

any attempt to use sound will cause the process using it to freeze and
not be killable.
The module is loaded with option model=thinkpad
Relevant output from lspci -v:
