Hi,
I was just running through the Device Driver book by Rubini. And
in the debugging techniques chapter it said I could run gdb as
following -

gdb /usr/src/linux/vmlinux /proc/kcore

This GDB was configured as "i486-linux-gnu"..."/boot/vmlinuz-2.6.17-10-
generic": not in executable format: File format not recognized

/proc/kcore: Operation not permitted.

You have to be root, I guess.



$ file /boot/vmlinuz-2.6.17-10-generic
/boot/vmlinuz-2.6.17-10-generic: Linux kernel x86 boot executable RO-
rootFS, root_dev 0x803, swap_dev 0x1, Normal VGA
Any idea what could be the issue ?

Oh, forgot to mention this. I am working as root only.
