This is also 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. 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. The serial console issue has its own thread on bugzilla https://bugzilla.kernel.org/show_bug.cgi?id=69751 and it happens also with kernels <= 3.8.13. For now I've seen that it's between 2.6.24.7 and 2.6.34.15, I'll do further tests and I'll report in the proper thread. Going back to the SAA7134 warning: dmesg: PM: Syncing filesystems ... done.
