Seems pretty long. Is this value based on any evidence (e.g., worse case length of time slices, etc.) or just a long value that happens to work? Might be nice to provide a bit more context in the commit message. E.g., extend the timeout for recovering vram bos from shadows on sr-iov to cover the worst case scenario for timeslices and VFs.
