reconnecting after hibernate

WINDBG
1

I am trying to debug an issue with my power dispatch routine using
windbg and 1394. When I set the target to hibernate I lose connection,
which is understandable, but the connection is not re-established and I
miss the breakpoint I am looking for when powering back up. My thought
is to put an assertion where I want the break to happen, is there a
better way?

Why don’t you just put a hard coded break point in your driver entry,
then when the machine boots up again, you will be able to set the
correct location of the break point that you want? Something like the
following:

/***********************************************************************
***

if the debugger is hooked up, lets break into it so we can load
our

symbols and set any break points we want. This will only happen
in

debug mode

************************************************************************
*/

TRAP();

Where TRAP is defined as follows:

#if DBG

#define TRAP() DbgBreakPoint()

#else // !DBG
#define TRAP()

#endif

I ve faced this issue too though it does not happen with S3 resume. Yes, a forced int 3 will workaround the issue but I think maybe this could be investigated by MS.

Here’s the response from the 1394 dev:

If he’s running Vista on the target, then it should work, but on
previous OS releases, there were issues reinitializing 1394 debug on
power state changes.

In addition, if what he’s debugging happens before 1394 debug was
reinitialized, then it won’t work. His best bet is to use serial for
this, if at all possible.
