Which is precisely why I told you to leave that terminal running with that command in advance, and examine the resulting file after crash and reboot. Better with REISUB.
Even better if you do it via ssh from another computer - way before the crash.
Most of the time when it locks up, I can't even switch to open apps. This morning I was able to, as I could see it coming. As I mentioned in another note, a can't ssh in when it happens. Most of the time, my only option is to power down and up. Even repeatedly hitting Ctl-Alt-Backspace usually doesn't work. That makes it difficult to do anything other than hit the power button. If I'm at the computer when it starts, I may be able to do something. If I'm away and then come back, the computer is completely locked up.
I repeat: you do this *before* it crashes. Hours or days before it crashes. And you leave it running, for hours or days. As long as it takes. After your machine crashes, and after you reboot, preferably with REISUB, you examine the file my proposed command wrote. As it will be large, you upload it to susepaste and tell the link. top -d 60 -b -o SWAP | tee less > somefile.txt -- Cheers / Saludos, Carlos E. R. (from 15.0 x86_64 at Telcontar)
