I've managed to narrow it down somewhat. The page corruption happens only when I've got the sound driver loaded: might be a DMA kind of thing that's killing me. Anyone got any ideas how I might narrow it down further? The sound modules loaded include ALSA's "snd_es18xx" with all the various OSS-compatibility modules. At the risk of making an inflammatory comment, I don't recall this kind of thing happening when I was using the equivalent OSS driver. N.B.: the ALSA driver only recently (in the past few months) became usable on the Alpha, and I made the switch to ALSA as soon as it was feasible to do so. I may try going back to the OSS driver (if it's still available) to see if the problem goes away. That would at least confirm my suspicions as to where the problem lies.
