Sorry. Bob was just saying this could be an important observation, but
it didn't get to everyone as the CC list got shortened. Cheers! -Tyson

The above patch doesn't make any difference for me as far as how the
ES1888 works. I get the same broken behavior as previously described.
I wonder if the difference between Bob and I (i.e., that I can get sound
working with patching while he cannot) might be that all along I've been
using CONFIG_ALPHA_GENERIC, while he has (possibly -- he will have to
confirm this) been using CONFIG_ALPHA_MIATA.
As I mentioned in the email I just sent out, I just finished discovering
that if I compile with CONFIG_ALPHA_MIATA, I can't get sound to work no
matter what I do (patched or unpatched es18xx or sb8).
When I compile with CONFIG_ALPHA_GENERIC I can get sound working (modulo
this new "Bad page state in process 'mpg321'" thing that started
sometime after 2.6.14) with either the patched es18xx or standard sb8.
Cheers! -Tyson
