SAA7134 warning during resume from S3: regression 3.8.13 -> 3.9.0

----Messaggio originale----
Da: [email protected]
Data: 14/02/2014 16.29

The full report is on bugzilla:
https://bugzilla.kernel.org/show_bug.cgi?id=69581

[1.] One line summary of the problem:

Kernel gives a oops warning during resume
from S3 sleep.

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

OS is Debian Lenny, with vanilla kernel. It happens the same after upgrade to Squeeze.
I've tried with kernels over kernels to find the point and I've found:
the latest working kernel is 3.8.13, the first failing is 3.9.0

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.
