I've already run memtest86+ for hours (not 24 ok... "only" 4/5h) and I
found this:
An easly reproducilble memory failure (single bit flipping always at
the same address) <---- this one goes AWAY disabling bank interleaving
in BIOS.
Another memory failure (different address, always one bit flipping)
isn't found by memtest86+: I found it with CONFIG_DEBUG_SLAB and
I "fixed" it with memmap=... boot option.
Now, these 2 problems are both in my first 256MB memory module, so maybe
it is really another memory failure.
BUT now that I'm back on 2.6.15.6 I'm compiling a LOT of big CPP
projects and I haven't seen a single GCC segfault yet.
Maybe I should retry with 2.6.16 and if I can reproduce the problem I
can start testing 2.6.16-rc1 and so on...
