Description Balazs 2009-07-11 18:50:00 UTC
Please extend Developer's Handbook '10.6 On-Line Kernel Debugging Using Remote GDB' section with a similar note:

It is maybe necessary to enable a serial port for remote kernel debugging. 
The "gdb: no debug ports present" dmesg message means there is no serial ports
configured for remote debugging. Edit '/boot/device.hints' and edit/insert:

hint.uart.0.flags="0x80" or 
hint.sio.0.flags="0x80"

For details please consult man uart(4) or man sio(4) depending on the serial 
driver is in use.

Thank you!
