I hacked something up a while ago, but it's not perfect. The code below
stops dumping too early IIRC, but I never got around to fix that. Maybe
someone wants to look at it and help debug, so we can put it into
gdbmacros.txt ...

Thanks,

define dmesg
        set $idx = 0
        set $seq = 0

        while ($seq++ < log_next_seq)
                set $buf = log_buf + $idx
                set $log = (struct log *) $buf

                if ($log->len == 0)
                        loop_break
                end

                printf "%s\n", (char *) ($buf + sizeof(struct log))
                set $idx += $log->len
        end
end

document dmesg
dmesg
Print the content of the kernel message buffer
