Subject: 2.6.1-rc1-mm1 - KGDB fails to breakpoint in Serial Mode


In 2.6.1-rc1-mm1, KGDB fails to generate breakpoints after the
initial one, in either built-in code or in modules.

I started the debug session as usual w
gdb vmlinux

The target then halts as expected in bootup

target remote /dev/ttyS0
c

causes boot to continue as expects

However, once running, the gdb break command against
the running kernel or a loaded module fails to result in a break.
The module start address was set as usual w add-symbol-file
which in turn matches cat /proc/modules.

I'll debug this myself if need be, but hopefully
there is some simple solution?

Thnx much,
johnh
