updated kernels / miata sound
This is actually a plea for updated status on getting sound working
correctly on the Miata platform with 2.6 kernels. The latest info I
have found to date is referenced in
http://lists.debian.org/debian-alpha/2004/11/msg00092.html
which has a similar subject line :-).
Back then, people described a problem where playing audio files
resulted in the sound driver getting stuck in a loop where approx.
the first half second of output was repeated. I confirm that the
problem still exists in 2006 with 2.6.17-rc4. Worse: in my case,
the looping audio resulted in the kernel reporting all kinds of
"Bad page state in process 'xxx'" errors, which ultimately forced
me to hit the reset switch to get everything cleaned up (tried a
soft reboot, which hung due to all the "Bad page state" errors).
I'm going to try 2.6.17-rc5 with Tyson Whitehead's patches (to
"sound/isa/es18xx.c" and "include/asm-generic/dma-mapping.h") and see
if that at least gets things up and running. I'm particularly wanting
to know if the ISA DMA problems on Alpha have been addressed in some
way other than the dma-mapping.h patch.
Possibly related, but probably not: /usr/sbin/hald from the hal-0.5.7-1
package is generating "unaligned trap" errors both at boot time and
whenever I load a hardware module. I'll go ahead and file a bug report
against that package.
