Hi all,

I have Ubuntu host running Ubuntu guest.
I use KGDB to debug the guest kernel PCI sub-system.
When I set breakpoints at the PCI device core functions (see below) and I try to "continue" from break to break the kernel boot fail and never complete.
Sending Sys Req key to the debugged kernel ( # VBoxManage controlvm Kernel-Devel keyboardputscancode 1d 38 54 22 a2 d4 b8 9d ) does not give me the clue why the kernel boot stopped if I jump from break to break.

Any idea is appreciated.

My .gdbinit file:
