logs and configs

I already submitted this bug here, because I see it during resume
https://bugzilla.kernel.org/show_bug.cgi?id=69351
but they told me to submint these driver issues one at once in the driver
sections.


[1.] One line summary of the problem:

Kernel 3.12.8 gives a warning during resume from S3 sleep

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

It happens also with 3.12.7, 3.12.6 and 3.13. 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 suspend. 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.

I put some log as attachment.
