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. > Using 2.4.8-ac8 with the patch from below at least works > more than stock 2.4.8-ac8 but I still get failures: specifically the > regular uhci driver seems to work perfectly except for the issue noted > above. 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 :) > But my uchi controller using the alternate uhci driver on > 2.4.8-ac8 results in an unusable system, and with the patch below kind > of works.

Meanwhile, try to remove that printout - it's only for JE uhci bughunt. -- Pete
