Summary: inserting maestro3 hangs system
Description:
Kernel hangs upon loading snd-maestro3 driver during hardware
initialization. The system only hangs if Windows was not booted prior to
booting Linux. So it seems that the Windows driver is poking the hardware
in some way that "helps" the Linux driver, and basically the ALSA driver
is not initializing the hardware correctly.

The attached patch linux-2.6-maestro3-assp-init.patch fixes this issue for
me. It seems that the driver tries to start the ASSP before downloading
the DSP code to it, which explains why booting Windows before warm-booting
Linux works. A warm boot must not clear the DSP memory, which allows the
ASSP startup to succeed.
The fix is to call the snd_m3_assp_init function to write the DSP firmware
into the ASSP chip before sending the RUN_ASSP command. I also made the
same fix in the OSS driver, but I did not test the OSS fix.
