Description
Guest: Windows XP, SP2. Host: Slackware 13.0 (also reproduced on Windows 7 host) Reproduced with these versions: v3.1.4, v3.1.6
Steps to reproduce: My computer -> Properties -> Advanced -> Startup and recovery. Ensure memory dump is on.
Set the following registry entry (assumes PS/2 keyboard):
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters] "CrashOnCtrlScroll"=dword:00000001
(Don't forget to reboot) This will allow you to 'blue screen' on demand.
Hold down right ctrl and press 'scroll lock' twice, to get crash dump.
Without additions installed, Windows writes a memory dump as expected.
With additions installed, the guest locks up, consumes 100% cpu and no memory dump appears. Sometimes (but not always) the machine recovers and reboots, but in either case no dump is written.
