The system is a Dual Athlon 2000+ MP on an Asus A7M266D w/3.5GB running an SMP kernel as of: FreeBSD 5.2-CURRENT #7: Wed Jul 14 19:36:00 EDT 2004 root@bling.home:/usr/CURRENT/sys/i386/compile/BLING panic: APIC: Previous IPI is stuck cpuid = 0; KDB: stack backtrace: kdb_backtrace(60737992,0,60752233,a9f44bf4,100) at 0x605782ae panic(60752233,60553c7a,607b5be0,1,2) at 0x6055d8a3 lapic_ipi_vectored(fc,1,a9f44c84,a9f44c84,64faf780) at 0x606e3233 ipi_selected(2,fc,a9f44c40,606f31c5,a9f44c84) at 0x606e8284 forward_statclock(a9f44c84,65282780,a9f44c6c,606e0048,a9f44c84) at 0x606e8199 pmap_rltacziynftirx(:a 9sfp4u4nc 8f4o,r0 ,56040f0b0f0c0108 ,a9f44c80,8) at 0x606f31c5 intr_execute_handlers(64f574f0,a9f44c84,a9f44cc8,606dc923,38) at 0x606e0048 lapic_handle_intr(38) at 0x606e2dca Xapic_isr1() at 0x606dc923 --- interrupt, eip = 0x608e9135, esp = 0xa9f44cc8, ebp = 0xa9f44cc8 --- acpi_cpu_c1(1,1,0,607b5be0,a9f44cfc) at 0x608e9135 acpi_cpu_idle(a9f44d14,60545f87,607b5c20,2,607351dc) at 0x608e8fe6 cpu_idle(607b5c20,2,607351dc,53,a9f44d34) at 0x606e4858 idle_proc(0,a9f44d48,60735072,328,0) at 0x60545f87 fork_exit(60545f50,0,a9f44d48) at 0x60545cb2 fork_trampoline() at 0x606dc5cc --- trap 0x1, eip = 0, esp = 0xa9f44d7c, ebp = 0 --- KDB: enter: panic I am a little worried by the line that starts with pmap_rltac. It appears to be the output of two interleaved messages, which I have yet to make sense of. At this point the machine is deadlocked and nothing short of a reset will get it to budge. Any ideas?
