2.6.22-rc6 bad page error (followup)

[Bob Tracy]

Same type of "stuff" happening with 2.6.22-rc7.  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.
