I have sent a patch upstream, adding the missing call to dump_stack() after the warning in ida_remove(). I have also applied that patch to our Factory kernel. Cristian, I invite you to update to the next Factory kernel which builds (doesn't seem to be the case right now, unfortunately) so that you get the stack dump in the event the bug happens to you again.
OK, here we go :-)
