Can you reproduce this with the latest kernel version, 2.6.21?
Created attachment 120628 [details] .config .config from gentoo-sources-2.6.21-r2 i'm about to build and test
I've tried compiling gcc-3.4.6-r2 and 4.1.2 as an stress test. Before with gentoo-sources-2.6.20-r8: - gcc-3.4.6-r2: fail in bootstrap - gcc 4.1.2: fail in bootstrap?(not sure) Now with gentoo-sources-2.6.21-r2: - gcc-3.4.6-r2: successfully emerged - gcc 4.1.2: /var/tmp/portage/sys-devel/gcc-4.1.2/work/gcc-4.1.2/gcc/loop.c:6370: internal compiler error: in var_ann, at tree-flow-inline.h:127 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://bugs.gentoo.org/> for instructions. The bug is not reproducible, so it is likely a hardware or OS problem. make[2]: *** [loop.o] Error 1 make[2]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.1.2/work/build/gcc' make[1]: *** [stage2_build] Error 2 make[1]: Leaving directory `/var/tmp/portage/sys-devel/gcc-4.1.2/work/build/gcc' make: *** [bootstrap-lean] Error 2 Will rebuild gcc-4.1.2 and report back.
Now its (gcc-4.1.2): Bootstrap comparison failure! ./insn-recog.o differs cp/tree.o differs fortran/parse.o differs
Do you have any memory testing utilities available? The errors seem random and are very likely to be the result of hardware problems. On x86/amd64 I'd recommend memtest here, but I'm not familiar with ppc.

Any news here? Do these problems still occur with latest development kernel (2.6.23-rc6 as of this writing)?
Apart from the fact that this smells like a hardware problem, the oops always being in the same place suggests otherwise. Please test the latest development kernel (currently 2.6.23-rc7) then report this upstream at http://bugzilla.kernel.org and post the new URL here.
(In reply to comment #16) currently testing with 2.6.23-rc7 (with enabled rtc and changed i/o scheduler cfq) memtester is running now... will retest with exact kernel-config copy.
Florian, Any results from your testing to report?
(In reply to comment #18) memtester is still running (Loop 324 with 480MB). openssl build results in an error, this is expected with only 23MB (from 503MB) left (i/o scheduler / oom-killer output in dmesg).
Bad news: machine restarted. But how?

So you're not able to build a 2.6.23 kernel to test with? If you're still running and old(er) kernel version, you should try to upgrade and see if you can still reproduce this behavior. This will also be asked if you report this upstream. If you manage to get a 2.6.23 kernel up and running, please post your .config and dmesg output here.
Created attachment 133430 [details] config for vanilla Linux 2.6.23-rc7 (In reply to comment #21) I'm already running vanilla-sources-2.6.23_rc7. Sorry, i didn't posted this earlier...

Please now file this bug report upstream as mentioned in comment #7. Post the new URL here when done. Don't worry about adding too many details, I'll add them once you have opened the bug.
oops, i meant comment #16
