Hello all, we have a new server - 2xOpteron 246, motherboard MSI-K8D Master-133 (chipset AMD8131) and 2GB ECC dual-channel memories Kingston, used fs is XFS. I installed SUSE LINUX 10.0 (X86-64). During compilation of large projects (for example linux kernel) and sometimes during system boot following messages in syslog appear (and compilation stops): Oct 14 10:00:32 linux kernel: ld[7703]: segfault at 0000000000000000 rip 00002aaaaaaae05c rsp 00007fffffc90170 error 4 Oct 14 15:01:43 linux kernel: grep[32266]: segfault at 0000000000000000 rip 00002aaaaaaae05c rsp 00007fffffa66800 error 4 Oct 14 15:01:44 linux kernel: grep[32355]: segfault at 0000000000000000 rip 00002aaaaaaae05c rsp 00007fffff958720 error 4 Oct 14 15:01:44 linux kernel: grep[32395]: segfault at 0000000000000000 rip 00002aaaaaaae05c rsp 00007fffffcd2600 error 4 Oct 14 15:01:44 linux kernel: grep[32458]: segfault at 0000000000000000 rip 00002aaaaaaae05c rsp 00007fffffed3e10 error 4 Nov 15 15:44:53 cedr kernel: ld[19959]: segfault at 0000000000000000 rip 00002aaaaaaae05c rsp 00007fffff807c90 error 4 Nov 15 15:45:50 cedr kernel: ld[21868]: segfault at 0000000000000000 rip 00002aaaaaaae05c rsp 00007fffffd78a80 error 4 All addresses are the same - 00002aaaaaaae05c. In /proc/self/maps these address belongs to /lib64/ld-2.3.5.so I tried check integrity of installed grep, binutils, gcc and glibc - all were valid. I tried to add/remove/change/move memory modules, running memtest, altering different BIOS settings (including load defaults), but the same messages always appear. When I tried to boot kernel with maxcpus=1 everything was ok. Now I installed SUSE LINUX 10.0 (i386) and running the same compilation - no errors appear. On this systen I tried to run x86_64 kernel (with all these i386 32-bit programs and libraries) and everything works also ok. Do you have any ideas, why programs don't run reliable on our computer under x86_64-smp? Is it possible, that problem can be in suse 10.0 bundled glibc-2.3.5 for x86_64?
