Just checked dmesg from before the crash but there is no relevant info. The
last entries are from a few hours before... not sure whether they got "eaten".
I could imagine that suspending prevents buffers to be flushed to disk.

I guess for now the only thing we can do is try different combinations of
software / desktop env and possibly kernel modules... until the problem isn't
reproducible a few days in a row.

Roberto, did you also use powertop to optimize battery life ?
Do you also have a BTRFS root partition ?
