It could be, but since it happens also on a completely different 
machine, with different processor, memory, video and an onboard serial 
port instead of the usb adapter, maybe it's an obscure kernel bug that's 
triggered only under some special conditions :-(

Maybe that could be the only way to see where it hangs (if it happens to 
hang on the virtual machine).
I'll see what debugging options VirtualBox has.
