might explain your problem.

I thought this was resolved in 4.1, but it looks like the problem still persists
there. At least I have reports from my workplace that 4.1.6 and 4.1.7 are still
affected. I don't know if there have been any relevant changes in 4.2.

Copying Herbert and Eric for additional input.

There was a separate bug discovered by Tejun recently. You need
to apply the patches

I assume this is on top of mainline ?

There is another follow-up but it shouldn't make any difference
in practice.

Any idea what may be needed for 4.1 ?
I am currently trying,
but I have no idea if that will help with the problem we are seeing there.
