site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com User-agent: Thunderbird 2.0.0.6 (Windows/20070728) I am using GDB kernel debugging over ethernet. Whenever I single step over a function call the target system locks up and never returns to the debugger. The keyboard debug break sequence and power button do not help once in this state. The target machine has to be power cycled. Target system is a quad core intel based mac running OSX 10.5.8. The GDB version on the debugger system is "GNU gdb 6.3.50-20050815 (Apple version gdb-966) (Tue Mar 10 02:43:13 UTC 2009)", using the 10.5.8 kernel debug kit. The debugger is fully functional except for the single stepping issue. Has anyone else seen this or have any idea what might be the cause?
