I'm experiencing fairly frequent crashes running Ubuntu on my laptop. This has actually been an issue on-and-off for a few years. There will be a few weeks or months where it happens often (up to multiple times per day) and then doesn't happen for long stretches.
What typically happens is that:
* the display continues to respond to input (mouse or keyboard)
* the icons in the tray (both top right and applications on the left) either disappear or turn into grey boxes
* audio sometimes cuts out if playing
* sometimes one of the open applications will pop up "this application is not responding, force quit or wait"
* if I try running (eg) htop in the termal I get "Input/output error"
* this state may last for a few minutes -- I've stayed on video calls for several minutes from this point before a full crash rebooting.
* I need to reboot.
* I don't see errors in the logs (journalctl or /var/log/syslog) from the time of the crash.
It's happening often this week and is extremely frustrating. Any help in getting to the bottom of this would be much appreciated!
