when I analyze the crash dump file(/proc/vmcore), crash utility show > me this error message, What does it mean exactly? > a bug or configuration error? > grub.conf > kernel /boot/vmlinuz-2.6.23 console=ttyS0,9600 root=/dev/sda2 ro quiet > crashkernel=2...@16m > > load cmd: > /sbin/kexec -p --command-line="root=/dev/sda2 irqpoll maxcpus=1 nousb" > --initrd=/boot/initrd.img-2.6.23 /boot/vmlinuz-2.6.23 > crash: > 4.1.1 > box: > Intel(R) Pentium(R) 4 CPU 3.00GHz > 4G RAM
> At what point did it happen? >Dave I insert a module which would trigger a kernel crash, in this module I use request_irq（irq, myinterrupt, ...）to register a irq on the nic, and in the function myinterrupt I just write something at somewhere (int *p = 00202020; *p = 10), the kernel would crash soon , but I cann't open the /proc/vmcore with crash utility after warm reboot, the error look like: --> crash: invalid kernel virtual address: 5fb001 type: "pgd page"
