Hello,
Recently, in developing our driver, we found the core dump did not work on the FBSD OS 6.2. It hung at the beginning of core dump when crash happened. We used the same configuration file to build the kernel on FBSD 6.0 (with SMP options). It worked. It dumped out the whole core file successfully. What is the problem? How to solve this is issue? Or what option should we add to get core dump work if we want to keep SMP option in the kernel configuration? The following are the prints when the dump hung. fatal trap 12 : page fault while in kernel mode cpuid = 1 ; apic id = 00 fault virtual address 0x8 fault code = supervisor read , page not present instruction pointer = 0x20:0xc059ac77 stack pointer = 0x28:0xe7fc2b30 frame pointer = 0x28:0xe7fc2b4c code segment = base 0x0 limit 0xfffff , type 0x1b = DPL0 , pres 1 , def32 1 , gran 1 processor eflags = interrupt enabled , resume , IOPL = 0 current process = 12 (swi1:net) trap number 12 panic : page fault cpuid = 0; uptime 3hours 51 minutes 18 seconds dumping 4030MB in 2 chunks chunk 0 1MB chunk 1 4031 MB (stopped and hung here) Our system: CPU: Dual Core AMD Opteron(tm) Processor 280 (2405.46-MHz 686-class CPU), 4x 1Gb RAM FreeBSD localhost.localdomain 6.2-RELEASE FreeBSD 6.2-RELEASE #1: Wed Jun 13 18:28:22 PDT 2007 [EMAIL PROTECTED]:/usr/src/sys/i386/compile/YONGSMPPOLL60 i386 Attached is our kernel build configuration file.
