I'm not sure if this is a correct mailing list for kgdb. If not could
anyone point me to the correct list?
I'm trying to use KGDB to debug kernel 2.6.14. I applied kgdb patch
linux-2.6.13-kgdb-2.3 to it (no all but core-lite.patch,
ppc-lite.patch, 8250.patch, cfi_annotations.patch and
sysrq_bugfix.patch). My cpu is MPC8343E. After choosing kernel
hacking options and compiling kernel, it just hangs and my gdb client
cannot connect to it. Following are message from linux booting and GDB
client, could anyone shed some lights on it? What could be the
problem? Thanks!
