This issue is really annoying so I'll try to debug it.

I think the easiest way to do it is to install a minimal system on a USB
stick and try to reproduce first in order to preserve my system.

Then I'll try to see if this issue exists in a previous kernel version
and if so, I'll do a git-bisect session.

I can't find a quicker way to do that although using git-bisect (which
implies several kernel builds) is a PITA.

Thanks.
