Hmm, I don't know there is already a fix for this, so waste a whole
morning :(. yes, your patch looks better.

Yes, this bug is causing a lot of people to waste time. I fielded an
internal request for this patch this afternoon. I appreciate we're
post-rc6 at this point, but it does rather suck to be releasing a kernel
which freezes on boot on this class of machines.

But it's not like the kernel every worked on this class of machines,
right? This is not something that was a regression from what I can see.

Unfortunately if this patch does cause any machine to break, these will
be machines that worked fine up until this point, so that would be a
regression, which is worse. Life sucks.

If, after a while, you think the change should go into the -stable tree,
I have no objection.

thanks,
