His tests are all with -stable, however. The #1 cause I have found of sig-10 sig-11 that are _hardware_ related have to do with memory system failures, quite often a bad cache chip or bad cache module and/or bad main memory. You _are_ using 60nS main memory right??? You do have 24 or less chips on each simm, right?? EIther of those violate the stated operating parameters of the PCI/I-P55TP4XE board. > I have a Seagate st32550N attached to it. Also, I'm running 0111 rev of the > ASUS bios. Phk just flashed his machine up to that revision and is now seeing soft (C-A-D) reboot problems, any such things going on with yours? I checked here and can not duplicate it here. > I also tried changing the main memory with standard 60ns simms, no change. > I've tried it with -current and -stable and still get signal 11's but less > frequently with -stable.
