Forgot to say:
- memtest86+ ran without problems for several cycles (once the laptop is booted
into Classic BIOS modes, for obvious reason).

RAM corruption is thus very unlikely



> - no filesystem corruption after checking for modification from RPM databse

Cron jobs also run periodic SMART tests (nightly shorts, weekly long) and btrfs
scrubs (weekly, too).
Data /filesystem corrupt is very unlikely to go unnoticed, even prior to the
RPM database compare.


Appart from aging component on the Mobo or on the power supply, I can't manage
to see where the problem could coming from.
