System bugchecks on break instruction (0x80000003)

Dejan_MaksimovicDejan_Maksimovic Member - All Emails Posts: 525

This happens quite often, almost always... WinDBG is connected to a VMWare Windows 7 machine, that is set up with VirtualKD.
If either my code has a DbgBreakPoint() or I get a debug break from another driver, I cannot continue execution after that point. F5/g, Step Into/Over/Out, Run to Cursor - all cause a bugcheck noting that 0x8000003 (debug break) exception was thrown.

Any ideas what could be wrong?

    I use VKD and Windows 7 and haven't seen this...Is it a recent update of Win7? Which versions of VMware and VKD are you using?

    I did not get this message in my e-mail, therefore apologies for a late reply.
    This is VMKS 9-12 (all had this issue). I cannot test any newer at the moment.
    VKD is 3.0, latest publicly available release.

    This happens on more than one Win7, but I think they were last updated about a year ago (it's a VirtualKD VM, for driver testing only, it has to be ready :))

    Update: also happens on a Win10 VM, but less often. This is the latest VMWKS that will run on my Nehalen laptop, so I cannot test VKS14. (ergonomics first :))

    Weird. I recently upgraded from VMWKS 12 to 15 and use the latest VKD. Never have this problem across multiple workstations (and targets of XP all the way through 19H1). You're cursed...

    I either figured a workaround, or was stupid all this time...

    F5 (g) causes the bugcheck, but gh (handle exception) does not. I
    would not have figured ir with any logic, considering the SAME
    assertion/break/etc. sometimes goes on, sometimes bugchecks after F5
    (and also bugchecks on one OS, but not on another).

    Hmm, spoke too soon :( This works in case I want to "gh" the breakpoint, however, if I want to step into the code, it still bugchecks :(
    How do I tell the OS the exception is handled, so I can step into the code, i.e. a "step into, with exception handled", like "gh" does for "Continue with exception handled"?

    Again, this does not happen always, but way more than I can afford to "retry agian".
