Re: oops in 2.4.18-3 kswapd?

[Jonathan Abbey]

My apologies to the list.  I see in the recent archives that a
page_alloc.c bug trace report with Nvidia driver installed was sent to
/dev/null on account of possibly erroneous code in the Nvidia module.

I'll cc: this over to [e-mail], but I don't see how they
could diagnose anything here, other than to be informed that there are
allegations of memory stomping in their binary kernel driver?

I did see the following, from Andreas Dilger:
|
| Please reproduce the error without the nvidia driver loaded, or report
| the problem to the nvidia developers.  Unfortunately it is impossible

| driver is overwriting memory elsewhere in the kernel and there is no
| way for anyone to check that.

So, um, poop.
