Hi all,
I'm seeing several segfaults on a couple of HP DL585 Dual Opterons, 8Gb ram 
each.

The segfaults are like this:
factorial[17031]: segfault at 0000000000020f31 rip 00000000004035ae rsp 
00007fffffe287e0 error 4
factorial[17034]: segfault at 0000000000020f31 rip 00000000004035ae rsp 
00007fffffc6f450 error 4
factorial[17038]: segfault at 0000000000020f31 rip 00000000004035ae rsp 
00007fffffdbd060 error 4
factorial[17044]: segfault at 0000000000020f31 rip 00000000004035ae rsp 
00007fffffb48fa0 error 4
factorial[17046]: segfault at 0000000000020f31 rip 00000000004035ae rsp 
00007fffffc2a7f0 error 4
ld[3997]: segfault at 0000000000000020 rip 00002aaaaad1a525 rsp 
00007fffffa8e960 error 4
ld[4234]: segfault at 0000000000000020 rip 00002aaaaad1a525 rsp 
00007fffffc3a1e0 error 4

This is only an example; often during some "make", also sed segfaults (!).
I've seen this with 2.6.12, 2.6.13.4, 2.6.14.2

distro: gentoo
gcc (GCC) 3.4.4 (Gentoo 3.4.4-r1, ssp-3.4.4-1.0, pie-8.7.8)

I've attached config.gz; I use Discontiguous Memory model, since Sparse Memory 
simply won't boot.

I've googled a bit to find some help, but while I've find only problems like 
mine, I've found no hints unfortunately.

Can someone give me some help?

Of course, more details are available.
