F16/F17: stacktraces in vmware-guests

[Reindl Harald]

has anybody else noticed this the last time?

i get this permanently in test-guests with F16/F17 while
the re-labeled 2.6.41 from F15 has no problems

all the loaded modules are from upstream-kernel (vmxnet3, pvscsi...)
and NOT third-party modules
