saa7134 warning during resume from S3

["valerio.vanni@inwind.it" <valerio.vanni@inwind.it>]

[1.] One line summary of the problem:

Kernel from 3.12.6 (did not try lower) to 3.13.2 gives a warning during resume 
from S3 sleep

[2.] Full description of the problem/report:

It doesn't happen with 2.6.24.7.
OS is Debian Lenny, with vanilla kernel. It happens the same after upgrade to 
Squeeze.

I suspend the machine with s2ram and it goes off.
During the resume it writes that warning, then it seem to work normally, 
except for serial redirection of console.

I use redirection of console to serial port (with lilo directive: append="
console=ttyS0 console=tty0") and I check the messages in another machine.
This stops working as soon as I resume. It begins to send mangled lines and 
it doesn't work again until the next full restart.
Only the serial redirection has this problem, the local console  works.
