I have kernel dumps for four panics, but >kgdb doesn't show any similarities between the panics (other than that they >are all #29). To add another datapoint: I just swapped the 350MHz PII in my Super Micro P6DGS (your generic 440GX dual slot-1 board) for a pair of PIII600Es. Since then, I have been getting panics under both 4.0 and 5.0 current from trap 29 that seem correlated to IDE disk I/O load. The first crash dump I grabbed showed that the faulting address was idle_loop + 64, which is at the cli instruction. Trap 29 could come from processor fault 19 (SIMD), an APIC, or PIC. Since cli isn't a SIMD instruction, I suspect the APICs or PICs but have yet to instrument and test this hypothesis. > tf_eip = -1071757093, tf_cs = 8, tf_eflags = 582, tf_esp = 0, > tf_ss = -8359936}) at ../../i386/i386/trap.c:586 >(kgdb) What do you get when you feed kgdb frame 3 info line * (void *)frame->tf_eip ? -- Home Page For those who do, no explanation is necessary.
