Spotted these in my dmesg, hopefully somebody is interested...

I'm pretty sure I fixed those so there should be a patch on its way to
or in mainline somewhere.

Oh,  OK.  I didn't remember seeing them mentioned before, but I must have
missed somebody else's post about it due to the lkml firehose effect. I've
moved these to my "whinge if it isn't fixed in the next -mmotm" queue.
