Hi, this is your Linux kernel regression tracker.

FYI, in case you missed it: there are multiple reports that this patch
is causing problems. A revert and a partial reverts are discussed:

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.

P.P.S.: Just to be sure, add this report to the regression tracking, too:
