I'm debugging a KEXT on a target system running 10.8.5 from a host (also
running 10.8.5) using gdb over Ethernet. On the target, I've set the nvram
boot-args setting is "debug=0x115 -v pmuflags=1".
However, even with "pmuflags=1", I still see the debugger hang when I
single-step from a breakpoint. This problem happens fairly frequently and the
only resolution I have is to power-cycle the target and start over.
What could be causing these hangs and what else can I do to keep them from
happening?
Thanks!
