[Solved] System hangs, kwin appears to crash, tty1 dead

Hello,
I have been subject to system instability in the past few days that I'm trying to diagnose. Something happens and then my computer progressively hangs until programs crash and I have to power-cycle the machine. I'm looking for help getting diagnostic data as to what is

When bad things happen I'm pretty sure kwin is dying because the plasma session goes down, and pressing ctrl-alt-f1 gives me a black screen with a (X) cursor.

Right now I'm keeping the system activity monitor open, along with a terminal, and have already logged into tty3 to try and debug the next time the instability hits. But I'm hoping for other suggestions to dump logs (or enable logs) to further make progress as to what's going on.

Re: [Solved] System hangs, kwin appears to crash, tty1 dead

I have to power-cycle the machine

This will prevent the journal from being synced to disk, hence

the timestamps are several minutes before the crash

And

pressing ctrl-alt-f1 gives me a black screen with a (X) cursor

means there's absolutely no need for this.

Also please avoid copy and pasting out of the pager (caps lines, '… The client was KWin::XdgTop>')

Re: [Solved] System hangs, kwin appears to crash, tty1 dead

Thanks for the ideas. It turns out I'm having nvme controller issues, causing my root volume to be re-mounted as read-only.
"nvme0 controller is down; will reset"
csts=0x3 PCI_STATUS=0x10

I've fully rolled back to before the troubles started happening. If that remains stable I'll see if updating my system triggers the bug again.
