Searching on the web shows this particular "4 bank 4" check when there are memory problems.

I was just wondering if bad kernel/module code could cause this, or if really indicates a HW system issue, and if anyone else has seen this running openib stress tests on X86_64...

Thanx,

Stevo.

The chipset and/or CPU detected "something bad" like a parity error or
something like that.

You'll need to know all the details of your system and find some
low-level documentation to decode the machine check output.
