Since upgrading to 9.0 I've been getting a handful of EHCI-related
dmesg errors and USB 1.0 performance from my ICH5's 2.0 ports. I
booted an 8.3 memstick to be certain it wasn't a hardware issue and
was able to push a few GB over USB at full 2.0 speeds. The system is a
PowerEdge SC1420 running amd64 (GENERIC); relevant dmesg below:

ehci0: <Intel 82801EB/R (ICH5) USB 2.0 controller> mem
0xcff00000-0xcff003ff irq 23 at device 29.7 on pci0
ioapic0: routing intpin 23 (PCI IRQ 23) to lapic 0 vector 54
usbus4: EHCI version ff.ff
usbus4: reset timeout
usbus4: reset timeout
ehci0: USB init failed err=18
unknown: reset timeout
device_attach: ehci0 attach returned 6

A full "boot -v" can be found here:

Any thoughts on resolving this would be appreciated.
