Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG Well, we still get one every day or two, at odd times. But I can ALWAYS make them happen by piping dump through gzip to ftp to a disk on a remote machine -- our usual backup procedure. Anyway, when I first reported this crash, I was asked what message appeared. Unfortunately, it flew by so fast that I couldn't tell what it said! So, tonight, seeing that it was a slow night and no users were on, I swapped the kernel for one with the debugger enabled and started the backup procedure. Sure enough, a crash. The screen said: Fatal trap 9: general protection fault while in kernel mode Instruction pointer = 0x8:0xf0176fb5 Stack pointer = 0x10:0xf0199000 Frame pointer = 0x10:0x0 Code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 Processor eflags = interrupt enabled, resume, IOPL = 0 Current process = Idle Interrupt mask = kernel: type 9 trap, code = 0 Stopped at idle_loop_0x3d: jmp idle_loop As I began to play with the debugger (I really didn't know the commands), I saw: wd0: interrupt timeout wd0: status 50 error 0 ...which may not have meant anything, but then again.... What does all of this bode? --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
