10028	Windows XP fails with !!Assertion Failed!! after enabling PAE	Maarten Jacobs		"I'm running VirtualBox 4.1.6 r74713 on Ubuntu 11.10. Guest OS is Windows XP.

I recently enabled PAE for this Windows OS - and VirtualBox regularly crashes with an Assertion Error:

{{{15:57:46.805 !!Assertion Failed!!}}}[[BR]]
{{{15:57:46.805 Expression: pPage && pPage->enmKind != PGMPOOLKIND_FREE}}}
{{{15:57:46.805 Location  : /home/vbox/vbox-4.1.6/src/VBox/VMM/VMMAll/PGMAllPool.cpp(5105) PGMPOOLPAGE* pgmPoolGetPage(PPGMPOOL, RTHCPHYS)}}}

I've looked around and found various items that refer to this similar issue (all closed for as far as I can see) - therefore I'm opening a new ticket on this.

I __think__ this is related to me turning on PAE support - but can't confirm that for sure. I've now turned off PAE to see if this makes a difference.

Log file attached. I'd appreciate it if somebody could get me some input on what this means?"	defect	closed	other	VirtualBox 4.1.6	fixed			Windows	Linux
