Happy holidays !

I have a toshiba satellite 2800-S202, with a yamaha sound
card YMF-754. From the lspci output I see:
<snip>

firmware request failed: -2

I see this in the changelog for 2.6.23-1 (I am only now
dnlding 2.6.23-2):

...

Could that be related?

Well, the card is YMF754, so if fits into the ones, and the
problem is also about firmware, so you seem to have
identified the issue...

If this is actually the issue, is there a way to work around
it? Maybe downloadind the firmware from somewhere and
placing into a specific directory? Maybe just like it's
done for ipw2100/ipw2200?
Roll your own kernel.org kernel. Using your existing .config
file, it shouldn't be too hard.
As the matter of fact rolling the Debian i386_none_686 kernel I
see that the config file has:

...
# CONFIG_SND_YMFPCI_FIRMWARE_IN_KERNEL is not set
...

just change that, I prefer with make menuconfig and recompile
as set forth in this list previously and voila! you have your
Debian kernel but with the firmware again for your soundcard.

Since the binary firmware has been "physically" removed, will that have any effect?


Good question. Don't know. Javier will have to let us know. My guess is that not too many people go through a recompile. In 2.6.23-2 there still is a "simple patch" that I have to disable. Why? Who knows, it apparently does not involve hw or arch of my setup.
