I think I fixed it long ago - we shipped it with Red Hat Linux 7.1 on ia64, and in errata for i386. I recall arguing about it with Georg Archer, and it was accepted into Linus tree. But perhaps not every hole was plugged.

Well, good. If you have an SMP problem - post to the list. I have 2 SMPs, one with uchi and one with ohci, which run well. People used to think that USB on SMP was a non-issue, but unfortunately companies like Dell started to ship rackmounted SMPs with USB keyboards :)

I think the JE uhci forgets to post a callback sometimes, so I'll look. Meanwhile, try to remove that printout - it's only for JE uhci bughunt.
