At this point i have run out of ideas. :-( This is checked already: - the complete hardware, except the 12 hdd. (smart reports, no errors at all, 4x ide + 8xSATA all 300GB.) - the SMP race. (checked with non-smp kernel) - APIC/ACPI (tested with non... kernel) - the e1000 driver (tested with realtek gige adapter) - the complete filesystem, OS (NFS-ROOT, and copy between nodes.) - the memory allocation proble, (checked with debug-kernel, and rised min_free_kbytes) The systems only service is nbd. (nbd-server serving md0, raid4 array) Anybody have an idea? Please let me know!
