Hello,
I tried to use eclipse for live kernel debugging.
I have a working set-up what work great with gdb by command line, hope to make it work with eclipse also...

<hw-set-up>
2 x86 pc connected by serial line (using moxa to usb)
After recompiling the kernel with all the debug options:
first pc is the dev station running eclipse while debugging vmlinux,
and the other is the target machine running the bzimage kernel with initrd;

<working with GDB>
on the target pc :
echo 1 > /proc/sys/kernel/sysrq
echo g > /proc/sysrq-trigger
and on the dev pc (gdb ):
//=====================================================//
//=====================================================//
> gdb vmlinux
......
.............
(gdb) target remote /dev/ttyMXUSB1
Remote debugging using /dev/ttyMXUSB1
kgdb_breakpoint () at kernel/debug/debug_core.c:1051
1051 wmb(); /* Sync point after breakpoint */
(gdb) l
1046 noinline void kgdb_breakpoint(void)
1047 {
1048 atomic_inc(&kgdb_setting_breakpoint);
1049 wmb(); /* Sync point before breakpoint */
1050 arch_kgdb_breakpoint();
1051 wmb(); /* Sync point after breakpoint */
1052 atomic_dec(&kgdb_setting_breakpoint);
1053 }
1054 EXPORT_SYMBOL_GPL(kgdb_breakpoint);
1055
(gdb) c
Continuing.
//=====================================================//
//=====================================================//

as you can see , GDB work great!!!
