Since installing 2.10 I've been getting intermittent BSODs on my Vista x64 host machine. The BSODs have happened 2-3 times during shutdown of my guest, about two times during startup of the guest, and maybe once during normal operation.
At first I thought it was a conflict with a previous Virtualbox install so I uninstalled everything Vbox and reinstalled. It seemed fine, and ran for 2 days straight, but then BSOD'd during shutdown of the guest, again.
I'm fairly certain every time it has happened it has said BAD_POOL_HEADER.
Attached are two minidumps and my most recent vbox.log. Minidump Mini122008-01.dmp is from a BSOD during shutdown. Minidump Mini122008-02.dmp is from a BSOD during startup. The windows debugger blaims VBoxNetFlt.sys and NTFS.sys respectively.
Let me know if I can be of any more help.
