I actually ran into some problems with my Alpha, and I haven't managed to g=
et=20
get it full operational again yet.  I replaced the CPU fan, installed the n=
ew=20
aboot, and left it trying to recover the filesystems.  It was an unhappy=20
story all around -- damn that CMD646 chipset, I was under the impression th=
at=20
driver had acquired some recent fixups.  Anyway, if this succeeds, I'll try=
=20
and compile up a new kernel with the patch when I get a chance.

With regard to the sound driver, the es18xx does endless looping on the fir=
st=20
second or so of sound on my box (a PWS500au) unless I apply my patch, which=
=20
just enables the alternative interupt detection code in the driver.  Even=20
then, though, I believe it still only works in 8bit mode.

The sb8 driver also works for me.  For this reason, I basically decided to=
=20
forget about my es18xx patch.  It doesn't get me anything the sb8 driver=20
doesn't give me, and it forces me to keep compiling my own kernels.

Cheers!  -Tyson

PS:  The Debian 2.6.24 kernel actually panicked on me (instead of infinitel=
y=20
looping on the first second of sound) when I tried the stock es18xx driver.
