I added:

    dyndbg="file net/ipv4/ipconfig.c +pflm"

to the end of the kernel command line arguments in grub and removed quiet. After booting I ran 'dmesg >after.txt'. I then rebooted and this time only removed the quiet argument, then ran 'dmesg >before.txt'. After stripping the timestamp column I diffed before.txt and after.txt and there was no new information (not even a line saying that the dyndbg was enabled).

Perhaps this is because the kernel image is stripped?
