Previous frame inner to this frame (corrupt stack?)
(this time I built the modules without debugging symbols).
Just to be sure that I did all thing properly below the steps I did:
1) returned original pmap.h (with KPTmap), rebuilt the kernel and rebooted
2) rebuilt with the patch virtualbox drivers and virtualbox (not sure this last
was
needed bu just in case...):
cd emulators/virtualbox-ose-kmod && make patch
applied this patch and your previous patch ("Patch to fix VirtualBox with
recent kernel versions")
built and reinstall
the same for emulators/virtualbox-ose
3) rebooted and started vm guest
virtualbox-ose-3.1.2_1 A general-purpose full virtualizer for x86 hardware
virtualbox-ose-kmod-3.1.2_1 VirtualBox kernel module for FreeBSD
