It seems there wasn't any progress to get this regression fixed (please let me know in case I missed something), but I guess nobody considered it urgent which is likely not that much of a problem in this case. Hence I'm moving this to the back-burner: #regzbot backburner: special case and UML a leisure pursuit for the maintainer Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat) P.S.: As the Linux kernel's regression tracker I deal with a lot of reports and sometimes miss something important when writing mails like this. If that's the case here, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight.
