A software bug is being reported, but since the software log says
the error is hardware, they try and close the bug. Notwithstanding the
entire bug focuses on the systems response to having the nvidia kernel
module loaded, and how it runs fine without the software, the entire bug
was closed as invalid because the mcelog says some of the errors are
hardware error. And, if mcelog say so, then it's got to be true! Sad,
really.

Am I missing something? You're asserting that the problem appears when
the nvidia module is loaded and goes away when the nv module is loaded?

The nvidia module is not open-source AFAIK and was provided by the
hardware vendor, so surely the hardware vendor is the right place to
report the problem. Also that specific driver is the subject of a
dispute with some kernel authors, so you can hardly expect them to spend
time on it when the open source driver is working. And yes, I know it
provides more functionality but that is because the hardware vendor has
not released sufficient information to build the functionality into the
open-source driver. So talking to the hardware vendor sounds like
exactly the right course of action.

Or did I misunderstand?

Cheers, Dave


Dave,

Yes, I think there is a misunderstanding. The problem *IS NOT* the nvidia kernel module it self, it works fine. What I suspect the problem *IS*, is the way the system handles the memory mapping, etc. *after* the module is loaded. Forget that the module involved is nvidia. It could just as well be called "The bunch of 1's and 0's, this many of them, that goes here when loaded" for purposes of this discussion.

What I _am_ saying is that on my Tyan board with its chipset/bios combination, and multicore AMD processors, the software (another module/kernel/pick you favorite part), is in fatal conflict with the driver and that for debugging purposes, there needs to be sufficient investigation to either rule in or rule out the problem.
