Created attachment 123231 [details] logs and configs [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.
From the log, there are two warnings related with i915 and saa7134 drivers.

I think you should apply bugs for these warning issues to related component separately.
For the saa7134 warning, perhaps send an email to the maintainer and cc the list is a good idea: $ ./scripts/get_maintainer.pl -f drivers/media/pci/saa7134/saa7134-core.c Mauro Carvalho Chehab <m.chehab@samsung.com> (odd fixer:SAA7134 VIDEO4LIN...,commit_signer:2/2=100%) Hans Verkuil <hans.verkuil@cisco.com> (commit_signer:2/2=100%) Ondrej Zary <linux@rainbow-software.org> (commit_signer:1/2=50%) Michael Opdenacker <michael.opdenacker@free-electrons.com> (commit_signer:1/2=50%) linux-media@vger.kernel.org (open list:SAA7134 VIDEO4LIN...) linux-kernel@vger.kernel.org (open list) For the i915 warning, please file a new bug to Drivers/Video-DRI(Intel).
For the saa7134: should I send an email with a referral to this bug or as a new thing?
I just saw that inside bugzilla.kernel.org there is a saa7134 section, can I open a bug there (ccing the mantainers) instead of sending an email?
