Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi, I have made some changes to my kernel and I am trying to install the new kernel. I have configured the kernel using config -f. While booting, the kernel panics with pagefault and repeatedly reboots. My question is how do I get a crash dump of the kernel? How do I find the problem? Here the log message that came on the screen before rebooting: Fatal Trap 12: Page fault while in kernel mode fault virtual address = 0x20 fault code = supervisor write, page not present Instruction Pointer = 0x8:0xf0194e2f stack pointer = 0x10:0xf3357d4c frame Pointer = 0x10:0xf3357dcc code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def 32 1, gram 1 processor ef flags = interrupt enabled, resume IOPL = 0 current process = 149 (sendmail) Interrupt mask = trap number = 12 Panic: page fault What does the current process sendmail means? Is it the one under problem? How do I get a dump of this kernel? How do I debug this?
