Hi Fedora Kernel list: I''m having a problem with a FC6 server running kernels kernel-2.6.22.5-49.fc6 and kernel-2.6.22.2-42.fc6. The hardware is: Tyan Tiger i7501R S2735. newest BIOS. Intel 32 bit Xeon 2.8Ghz 533 FSB sSpec SL6VN 3G DDR reg ECC RAM. 2 * 80GB IDE DASD. The interesting bit: The server resets, no kernel panic, no oops, nothing but a reset. I have *.debug in syslog, and see no errors in syslog or in dmesg. The resets seem random. They can occur at any point within a couple hours of boot. This ONLY happens when I have two processors on the board. I have rotated multiple processors in the second socket, and from the second socket to the primary socket. They only way the server is stable is when it has only a single processor. Any assistance would be greatly appreciated. Thanks; E!
