Sorry about the duplicated report, I must have missed the fix in the
changelogs. I've been following closely in general partly because my
machines are very sensitive to i386 interrupt changes, and I need to
help do testing and report things early as you're not likely to have a
similar machine.
Since it's where the fixes are going, it looks like I'd better use
your tree. I'll follow up once I've updated and had time to test.
(They are unfortunately very slow to boot.)
Thanks,
Bill
