Jakub, thx for bringing this up, I had "look  into this again" on my
todo list for some time already. Out of interest: where where those reports?

Besides the one the quoted mail is about
( ) I'm aware of two
other reports that look similar and might or might not be related (hard
to tell without domain knowledge, I guess it might be just similar

Gregory, are you aware of these regressions? Is anyone working on them?
Or is this faulty hw or something like that?

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.
