Changes since v10: - rebase over recent Linus master (rc6+) - fix stuck gdb pagination during modprobe related symbol reloading See http://lkml.indiana.edu/hypermail/linux/kernel/1210.0/01598.html for the original description and git://git.kiszka.org/linux.git queues/gdb-scripts for the latest version. On the gdb upstream front there is good and bad news again. The good news is that the regression reported in the last round was fixed now [1]. The bad news is that upcoming 7.9 has a new regression that is even causing a crash of the target kernel [2]. So the recommendation is still to stick with gdb 7.7.
