[Why] When host trigger a whole gpu reset, guest will keep waiting till host finish reset. But there's a work queue in guest exchanging data between vf&pf which need to access frame buffer. During whole gpu reset, frame buffer is not accessable, and this causes the call trace.
[How] After vf get reset notification from pf, stop data exchange.
