Yes, I've just verified that.  (We just brought the machine up on the

Here's the boot messages:

I've got another one of these cards that I can bring up in a test machine
on Monday to help debug this.

The problem is 100% repeatable in the machine I set up yesterday (which,
unfortunately, I can't mess with), but assuming I can duplicate
it in another machine (with one of the cards that had problems in the
first machine) on Monday, what do you need from me?  I'm willing to
help out in whatever capacity to see this get fixed in 1.5.  (And 1.4.3,
if the problem exists on that branch!... I can test that too, if need be.)
