SubjectOopses with 2.1.8
Date

Hi,

I've posted some days ago oops report on my box with 2.1.8.
Nobody answered so i must be the only one seeing this.

I've not been able to run a 2.1.8 kernel without crashing it
in less than 10 minutes..

First kernels 2.1.8 were build with gcc 2.7.2.f.1 (gcc + fortran g77),
I then recompiled stock 2.7.2 in case there was some obscure bug added
in the backend of gcc by g77. Kernel compiled with stock 2.7.2 crash as well.

Doing 2 hours of memtest86 didn't find any problem with my RAM, my CPU
fan is still running.

Here is one of the latest oops:

went through colrm and ksymoops:

Using `/boot/SysMap/System.map.218.96.11.12.14.44' to map addresses to symbols.

>>EIP: c012fb25 <load_elf_interp+189/2e0>

What are thos nop'ses replacing the movl?? Self modifying code? Shitty DRAM?
Something in kernel space writing stuff around?

Sometimes oops come from dcache.c (dont remember exactly where)

Could a kind soul try this .config, it may show up some light on this.

Note: I don't start GPM at startup anymore, and never launch it
with 2.1.8, (gpm-1.10)
