For now, anyone seeing a panic message like: 8254 redirect via APIC pin0 impossible! should comment out i386/include/smptests.h: #define APIC_PIN0_TIMER Please don't do this unless you encounter this panic, then try it and report results. Include your mptable (-dmesg not necessary). -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD
