MS security update KB956841 makes XP Guest hang at splash screen

[ridcully]

Having set up a fresh install of a XP pro SP3 VM I found out - by testing around with restore points and user defined choice of updates - that after installing the patch KB956841 with Windows Update the VM will hang on reboot, showing a frozen splash screen. All other updates since SP3 work just fine. I wonder why there are no reports of that problem yet, since the update is from 9/8/08? Host is Ubuntu 8.10 x64, Guest with ACPI, IO APIC, VT-x/AMD-V,PAE/NX active, no Nested Paging. Everything is freshly installed.

Attach the VBox.log from such a session please. Also try if disabling PAE makes any difference.

Just set up a new test environment with PAE disabled - same effect, always reproducable. Log added.

Please reopen if still reproducible with VBox 3.2.6.
