In any case, with the silly syzbot mmap stuff fixed up, I'm not seeing anything odd. A few tests will time out as they simply run too slowly emulated for me, but apart from that, seems fine. This is running with Helge's patch, though not sure if that is required running emulated.
I'm seeing two problematic tests: test buf-ring.t generates on console: TCP: request_sock_TCP: Possible SYN flooding on port 8495. Sending cookies. Check SNMP counters.
