Summary:                    au8820 hangs the system at some occasions
Description: 
At some occasions the system hangs without any means
to recover other than reset button. No mouse, no pings and
even the alt-SysRq feature doesn't help.
As a result I reboot the system a few times a day (sometimes).
The problem is present in 2.6.5, 2.6.6 and 2.6.7 kernels at
least.

I'm sorry, but I no longer have that PC, so I can not check if this is
fixed. I saw a number of problems with the au88x0 driver on 64 bit
platform - it used to cause kernel panics back then until I made a small
change (it was something related to long being 64 bit on amd64 - I think I
even sent the patch once). Although the hangs were on both 32 and 64 bit
kernels.

It's possible for au88x0 to hang the computer if you open too many
applications especially OSS applications on 32/64 bits machines. 

This hang is more likely to happen in au8820 than au8810/au8830 since
au8820 only has 16 MIXIN and au8810/au8830 has 32 MIXIN

open a flash, tons of error messages are generated in the system log
immediately.
