Hello,
I now have a 2.6.6 kernel with kdb; were I can verify that vmlinux has kdb
symbols with nm.
My kdb .config options are:
CONFIG_FRAME_POINTER=y
# CONFIG_4KSTACKS is not set
CONFIG_KDB=y
# CONFIG_KDB_MODULES is not set
# CONFIG_KDB_OFF is not set
CONFIG_KDB_CONTINUE_CATASTROPHIC=0
However, when I boot and get the getty prompt, Ctrl-A has no effect.
This is straight from the penguin 2.6.6 + kdb patches referenced below.
I tried this both with default VGA console and redirected to a serial port
with getty enabled. There was some thought of changing the entry key at
one time because Ctrl-A conflicts with emacs/shell editing, but I haven't
seen any reference in the documentation and web site for this change.
Any thoughts?
