kernel bug in 11.3-STABLE causes frequent crashes (Scott Bennett)

Personally, with old hardware, I'd be inclined to check the power
supplies and mobo' for decoupling/storage capacitor problems (bad-cap
issues) and rectify them.
The power supply is the real heart of any system, not the CPU. Plus,
that in turn relies on reliable memory, that in turn relies on clean
power. Get the picture. Similarly, the associated cooling systems,
keep fans and filters clean, and heatsink fins clear. On very old
systems (10 years or more) the thermal bonding between CPU and heatsink
could be also failing. I've even seen the heatsink partly hanging off
the board, as a plastic clip had failed with age (and heat, due to a
Then if the trouble still persists, boot a current copy of memtest86,
and let it run the full gamut of tests for several rounds, without fail,
just to know the basic hardware is OK.
Of course, if memtest86 croaks in odd ways before it really gets going
then you may have a failing CPU. But swap some memory modules around,
so that where it's first loaded into uses "different" chips than it was
before, before you point fingers at the processor.
AMD processors don't like heat (they die.) Intel at least just slow
down (to a crawl) to prevent them cooking themselves.
Hope you get to the bottom of things.
