Ah, so we found and fixed these ?

Linus, those bugs are actually a regression from when we didn't use the
new timer code (which isn't that long ago). It would be nice to have the
fixes in .27 (and thus in the various distros that will derive from it)
but I would understand if the size of the patch made you choke that late
in the -rc cycle... In which case we'll be in for more backports :-)

Cheers,
Ben.
