Hi.
Some time ago I had problems with my PC not being able to resume from a suspend to ram once in a while. Sometimes it was more often, sometimes rarer, but always happened.
Before I had: Gigabyte GA-EX58-UD3R, Intel i7 920, NVidia GeForce GTX285. Recently I've updated my PC with: Z170A GAMING M7, i7 6700-K, integrated GPU for Linux and R9 280x as passthrough for a guest operating system. It seemed my problems ended until it turned out that they just became rarer. Occasionally I resume my PC only to hear the sound of fans and disks spinning up and nothing more. The screens are off and the USB ports are off.
My MB has an LCD with the current POST message, but it just displays the CPU's temperature (within idle range), which means, according to the motherboard, that everything is fine. Obviously it's not. So probably there was a kernel panic. My question is how can I debug this? I have no serial port on my MB. There is a TPM header below the last PCIe port, which has some LPC data pins according to the manual, but I have no idea if I can use that or even if the Linux kernel has drivers for that. What other ways are there to debug a kernel panic in such early stage of resuming from RAM?
This problem is really annoying and has cost me a lot of my work (sometimes it just doesn't happen for so long I forget to save before suspending).
EDIT: spelling errors
