Comment (by bonefish):
Replying to [comment:6 grahamh]:
> OK, the gdb end of the system is in the clear. It's doing the single
step as requested, and the B_DEBUGGER_SINGLE_STEP message it gets back has
cpu_state.eip == 0xffff0114, which is somewhere either in the commpage or
just off the end of it.
Yep, that address is the syscall trampoline in the commpage. BTW, the
kernel debugger knows it and prints the stack trace accordingly. If gdb
delivers garbage, it's usually a good idea to check from KDL.
