[Pkg-virtualbox-devel] Bug#722194: virtualbox: VERR_SYMBOL_NOT_FOUND: SUPR0SuspendVTxOnCpu

[Jan Nordholz]

Package: virtualbox
Version: 4.2.16-dfsg-2

Hi,

I cannot resume my VMs anymore. Virtualbox terminates any attempt (regardless
of the instance or type of guest OS) with

] 00:00:11.973191 AssertLogRel /tmp/buildd/virtualbox-4.2.16-dfsg/src/VBox/HostDrivers/Support/SUPLib.cpp(1726) int supLoadModuleResolveImport(RTLDRMOD, const char*, const char*, unsigned int, RTUINTPTR*, void*): <NULL>

VMMR0.r0 really lacks that symbol... but vboxdrv.ko has it, so I suppose
this is correct:

] jcn at inti:/usr/lib/virtualbox$ nm VMMR0.r0 | grep SUPR0Sus
]                  U SUPR0SuspendVTxOnCpu
] jcn at inti:/usr/lib/virtualbox$ nm /lib/modules/$(uname -r)/extra/vboxdrv/vboxdrv.ko | grep SUPR0Sus
] 00000000000004c0 T SUPR0SuspendVTxOnCpu

I have reloaded the modules, rebooted the system etc.; what is the preferred
way of debugging this? Can I enable more debug messages, especially of the
kernel layer, or do I have to do a full debug-enabled rebuild? (And is there
a comfortable way of doing that, as I couldn't find any debug-related options
in debian/rules?)

My system is unstable (experimental for a few selected packages), my kernel
is git HEAD, and virtualbox is at 4.2.16-dfsg-2.


Thanks,

Jan
