3.2.35 problem with M5A97 PRO ram: bad_page free_pages_prepare mem_init

despite this errors machine runs ok and rather stable.

Is this problem already known?
What can be done to debug it so we can fix it?

Yes, also, if your DRAM supports ECC, try enabling it in the BIOS.
This board should support ECC. Then, enable CONFIG_EDAC_AMD64 and
CONFIG_EDAC_DECODE_MCE to check whether it catches any DRAM errors.

If your DRAM is non-ECC, try consecutively swapping out a DIMM each time
and booting to see whether removing one of the DIMMs makes the errors go
away.

HTH.

Thank you;
On vanilla 3.2.36 there is the same problem.

Also problems happen on each boot so not random memory error, but I will
try to swap rams, run memtest and so on.

Turned out it was just a hardware problem after all.
Solution is simply to try good memtest86 memory tester and swap out bad
chip.

Sorry for the trouble, thanks.
