Hi,
One of our users is having a NULL ptr dereference upon loading thesnd_hda_intel module with 20090624's snapshot. There's only one commitafter that date in patch_sigmatel.c so I didn't tell him to try with thelatest snapshot but if you think that the bug may be related to anotherpart of the ALSA codebase, I can make him try the latest snapshot.
I'm attaching the alsa-info output on a working system with 1.0.18a. Thekernel version in subject is 2.6.25.20.
Thanks,Ozan
