Hi guys. This commit:
commit 1cedae72904b85462082dbcfd5190309ba37f8bd

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.

For the record, this bug is fixed in the thread
[GIT PULL] hw-breakpoints fixes. (Less than one day!)
Thanks Frederic!
