kernel panic on 10.6 "beta" on VBoxDrv.kext loading -> fixed in svn

[cmf]

virtual box 3.0.0/3.0.2 causes a kernel panic as soon as a virtual box driver/kext gets loaded (i.e. a vm is started). this happens on all 10.6 "beta versions" (10.0.0.b1/b2/b3).

most probable reason: undefined symbols, virtual box was apparently built against 10.0.0d3/d4 (pre-wwdc kernels).

# kextlibs -all-symbols VBoxDrv.kext
For all architectures:
    com.apple.kpi.bsd = 10.0b3
    com.apple.kpi.iokit = 10.0b3
    com.apple.kpi.libkern = 10.0b3
    com.apple.kpi.mach = 10.0b3

For i386:
    417 symbols found in one library kext each:
...
    7 symbols not found in any library kext:
	_get_task_map
	_cpu_number
	_mp_rendezvous_no_intrs
	_vm_protect
	__ZN12IOUserClient22_RESERVEDIOUserClient1Ev
	__ZN9IOService19_RESERVEDIOService5Ev
	_kernel_map

For x86_64:
    392 symbols found in one library kext each:
...
    5 symbols not found in any library kext:
	_cpu_number
	_kernel_map
	_get_task_map
	_vm_protect
	_mp_rendezvous_no_intrs

Thanks for the report. We have updated our internal build boxes to the latest version. You should be able running it again with the next upcoming minor release (3.0.4).
