http://oss.sgi.com/projects/kdb/download/ix86/ contains a patch for kdb v1.5 against 2.4.0-test9-pre8. Changes from kdb v1.5-beta2. * Upgrade to 2.4.0-test9-pre8. * Fix premature NMI oops on machines with large numbers of cpus. This version of kdb also includes :- * NMI oopser for uniprocessors. This builds on Keir Fraser's excellent patch for activating the local APIC on P6 systems and (ab)uses the local APIC to generate NMI on systems which have a local APIC but no IO-APIC, typically any P6 and above uniprocessor. So you poor developers with uniprocessors can now get diagnostics when the system gets into a spin loop. On the Processor configuration menu, select 'APIC and IO-APIC support on uniprocessors'. That option will detect the local APIC if it exists. See the help for 'NMI watchdog active for uniprocessors' and Documentation/nmi_watchdog.txt. Expect the configuration method and the use of /proc/sys/kernel/nmi_watchdog to change in future. Ingo Molnar and I are discussing how much of the NMI oopser for uniprocessors should go into the standard kernel. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
