Hi,

I've recently returned to messing around with CE 6.3 hacking on my new Windows 8 64 bit laptop, and the DBVM crashes my laptop sometimes.

It was only today that I tested, and these are the results (running ce-i386.exe):
1) Kernel debugger, stealthedit v2 plugin ---> system crash
2) Windows debugger, stealthedit v2 plugin ---> system crash
3) Windows debugger, no plugins ---> DBVM loads
---> After step (3), I switch back to Kernel debugger and stealthedit v2 plugin, and there's no problems.

Obviously, the issue seems to point at the stealthedit v2 plugin, but I can't guarantee my test. I might have forgotten to switch back to Windows debugger in (2)...

Anyway, I just wanted to ask if this is a known issue? A few days later I might forget to switch back the options before switching on the DBVM, but for now I'd rather not constantly crash my laptop just to test on this Razz

Thanks!


*EDIT*
Never mind, I've identified the real problem: running the DBVM when windows is still loading up (e.g. 1-2mins after logging into user account) will cause system to crash. After logging in and waiting a few minutes or so, definitely no crash.

I assume it's DBVM is requesting access to something which hasn't started up yet...

Just wondering. What kind of crash was it ?(BSOD/system freeze?) And what cpu vendor ?(AMD/Intel)

DBVM doesn't request anything from the system, but if it encounters something that hasn't been implemented yet (like another virtual machine) it may bug out

It's the windows 8 BSOD ("pc ran into a problem, needs to restart etc"). In the error it said it was related to the dbk64. Also, I'm using intel i5.

Doesn't pose any problems to me now that I know, but a bug's a bug Very Happy

This is more a driver issue instead of dbvm. (if dbvm messes up, you'll just get a full freeze or windows wouldn't even know what caused it, cpu timeout)

If you get that bug again, configure windows to generate a memory dump of the kernel, and next time it happens upload the dump somewhere so i can inspect dbk64.sys and it's memory/stacktrace to see where it goes wrong.
