I have a situation that may or may not be related, but it makes 2.6 USB unusable, so I'll just report it.
I have USB lockups with various 2.6.3 variants, including 2.6.4-rc2, on a VIA KT600 (Via 8237 south bridge). Linux 2.4.25 and newer (BitKeeper version) behave well, so does FreeBSD 5-CURRENT on the same computer (dual boot), and apparently the 2.6.3 kernels are fine on a VIA KT133 (Via 82C686 south bridge - older variant with UDMA66 only).
During a scan attempt with an Epson 1650 (USB 1.1, hence UHCI) I caught these logs in dmesg, the USB subsystem is dead now (2.6.4-rc2). I don't have USB 2.0 hardware so I cannot check if EHCI would be fine.
