My system seems to crash from time to time. I still don't know what causes it.
If I leave it untouched for a few hours, sometimes, it crashes.
To resume, I have to force a reboot by unplugging the power cable (not even pressing the power button for N seconds seems to work).
Then, it seems to work just fine (after displaying some error messages about lost or orphaned inodes at boot). Until, one day, it happens again. When? I never know. It seems to follow some strange and unpredictable pattern.
Where should I start investigating?
Thank you all who contributed.
I was hoping for some log that could maybe save some info when in a hurry, sensing an eminent crash or an emergency, but that doesn't really make sense, does it? - If it crashes, it crashes. There's probably no time to dump anything to disk. Otherwise the crash would have been prevented.
Anyway, some paths have been opened for when I have time to dig in a little bit deeper.
I'll quickly find something else to annoy you ASAP. ;-)
