I have 1GB ram, so maybe one of my dimms is bad or maybe there's a highmem bug in the 2.4.X kernel. The crashes in my previous emails today were due to using the latest alsa modules (loaded, but not used by any application) with a HIGHMEM enabled kernel. I appear to have no problem using alsa when HIGHMEM is disabled. Apparently, I'm not the only one having problems with alsa and highmem (http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg13918.html). I would be willing to work with a kernel developer to better isolate this problem and test a patch. Thank you, Peter Santoro
