I am debuggin a hung system where the display is frozen and keyboard does
not respond. However I doubt if the system is hung since my dpcforisr gets
executed. This was just a background.
My question being, is there a way to ascertain if the OS thread scheduler is
still working… in other words are threads still being switched around.
This is a debug only purpose and I have no interest in hacking / security.
Also one could argue that there are other ways to debug the scenario that I
have presented but this is just out of academic curiosity.
thanks

Ok
!running -it
!thread ETHREAD (as from !running) successively
and then compare the User/Kernel mode time spent seems to do the trick for
me.
