Hi Every few years I get a kernel upgrade that breaks my server. This time the first oops (and the last to make it to syslog) seems to be v4l related. After this I get more on the console at intervals, but the server is unusable. Returning to 4.5.2 fixes things. Oops and dmesg (from 4.5.3) attached. Looking at source control 922ff7af18370b752204c03e75e3dc3a2c50127d and ef468ad540f990e0f479a7548aea7dd089fdbd5a look like likely culprits. I might try reverting these and trying again, but the boss at home is grumpy enough that my quick restart turned into an hour of faffing before I reverted, so I may not do this over the weekend. Cheers David
