Compiling and installing the 1.0.0pre1 ALSA driver works fine, but if I do a 'modprobe snd-au8820', the computer locks up instantly (can't even ssh in from another computer). Going back through recent CVS commits, I found that the problem is caused by the changes described in the following alsa-cvslog message: http://sourceforge.net/mailarchive/message.php?msg_id=6552838 Specifically, the problem is caused by the changes Takashi made to au88x0.h and au88x0.c to eliminate calls to pci_request_regions() and pci_release_regions(). If I revert those two files to their previous versions, the driver compiles and works fine. I'm not an ALSA driver guru, but I didn't see anything immediately wrong with the changes introduced by the above CVS commit that would cause such a drastic kernel error. Perhaps someone more familiar with the code in question could take another look at those changes?
