Hi, I'm experiencing a reproducible kernel panic that would be really nice to debug, but unfortunately no core file is getting generated. I don't have console access either. All I can get so far is this, from syslog: Aug 23 19:51:38 <kern.crit> estranged kernel: Aug 23 19:51:38 <kern.crit> estranged kernel: Fatal double fault: Aug 23 19:51:38 <kern.crit> estranged kernel: eip = 0xc0593b2e Aug 23 19:51:38 <kern.crit> estranged kernel: esp = 0xe5583fe4 Aug 23 19:51:38 <kern.crit> estranged kernel: ebp = 0xe5584010 Aug 23 19:51:38 <kern.crit> estranged kernel: cpuid = 0; apic id = 00 Aug 23 19:51:38 <kern.crit> estranged kernel: panic: double fault Aug 23 19:51:38 <kern.crit> estranged kernel: cpuid = 0 Aug 23 19:51:38 <kern.crit> estranged kernel: panic: 0xc4263b40 must be migratable Aug 23 19:51:38 <kern.crit> estranged kernel: cpuid = 0 Aug 23 19:51:38 <kern.crit> estranged kernel: panic: 0xc4263b40 must be migratable Aug 23 19:51:38 <kern.crit> estranged kernel: cpuid = 0 [SNIP - above two lines repeated alot] Aug 23 19:51:38 <kern.crit> estranged kernel: cpuid = 0kernel trap 12 with interrupts disabled Aug 23 19:51:38 <kern.crit> estranged kernel: panic: Aug 23 19:51:38 <kern.crit> estranged kernel: 0xc4263b40 must be migratablekernel trap 12 with interrupts disabled Aug 23 19:51:38 <kern.crit> estranged kernel: kernel trap 12 with interrupts disabled Aug 23 19:51:38 <kern.crit> estranged kernel: cpuid = 0 Aug 23 19:51:38 <kern.crit> estranged kernel: kernel trap 12 with interrupts disabled Aug 23 19:51:38 <kern.crit> estranged kernel: panic: My dumpdev is set: $ ls -l /dev/dumpdev lrwxr-xr-x 1 root wheel 11 Aug 23 19:56 /dev/dumpdev@ -> /dev/ad4s1b But savecore reports: Aug 23 19:56:34 <console.info> estranged kernel: No core dumps found. Any advice for getting a core file? :) Thanks, Aragon
