You may run your kernel under gdb in qemu like

qemu-system-arm -M n810 -kernel linux-omap-2.6/arch/arm/boot/zImage -s

load symbols from your vmlinux with gdb command

symbol-file linux-omap-2.6/vmlinux

and at certain point break into gdb by ^C and dump system log buffer
with gdb command

dump memory kmsg.log log_buf log_buf+100000
