Hi guys. This commit:
commit 1cedae72904b85462082dbcfd5190309ba37f8bd Author: Frederic Weisbecker <fweisbec@gmail.com> Date: Wed Dec 2 07:32:16 2009 +0100
hw-breakpoints: Keep track of user disabled breakpoints
breaks debugging with gdb (at least gdb-7.0, anyway).
For example, if you start firefox with the -g flag, it will run in gdb. When running a kernel with this commit, gdb will stop with the message: "Couldn't write debug register: No space left on device". When trying to quit gdb by typing 'q', the process hangs forever.
This seems to be related to the size of the program being debugged. Running /bin/ls with gdb, for example, works normally. But large programs like firefox, thunderbird, or evolution (from gnome) all trigger the same error message.
Can anyone reproduce this?
Thanks.
