Does this C producer depend on state of the machine? i.e what is the status of vhci_hcd - are there any devices attached? I can see the problem looking at the code and fix is easy. However, I would like be able to reproduce it and verify the fix works. Also this would be a good regression for the driver I could consider adding to selftests. thanks, -- Shuah
