Anything installed recently.... Hardware or software? -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx <redhat-list-bounces@xxxxxxxxxx> To: General Red Hat Linux discussion list <redhat-list@xxxxxxxxxx> Sent: Tue Dec 05 18:43:34 2006 Subject: Failure to boot with SMP kernel on x86_64 SMP system ... Hi, Folks ... One of my Sun X4100s was hung this morning. All of them are running RHEL 4 update 4. On rebooting with an SMP kernel, it consistently hangs after printing the below to the console: =========================================================== powernow-k8: Found 4 AMD Athlon 64 / Opteron processors (version 1.50.04-rh) powernow-k8: MP systems not supported by PSB BIOS structure powernow-k8: init not cpu 0 powernow-k8: init not cpu 0 powernow-k8: init not cpu 0 ACPI: (supports S0 S1 S4 S5) ACPI wakeup devices: PCI1 USB0 ETHR USB1 Unable to handle kernel NULL pointer dereferenceFreeing unused kernel memory: 192k freed ============================================================ All of the systems I have are running the same kernel (2.6.9-42.0.2.ELsmp), but I also tried booting it with 2.6.9-34.ELsmp kernel, with the same exact result. I can boot it fine using the "non-SMP" kernel, but of course, I wind up with only one CPU. This kernel isn't new to the system; it has been running fine with it for a while. I ran the hardware diagnostic DVD, and it found no hardware problems. So, I'm fishing for ideas here ... anyone got any?
