ultranav usb keyboard panics on bootup -- stuck

[Craig Butler]

Hi All

Anybody know how I work around the following panic ??

panic: ohci_add_done: addr 0x7fef1c30 not found
cpuid = 0
Uptime: 1s

I have just purchased a new Lenovo ultranav usb keyboard from .
(My old ibm ps/2 one died)

The panic is definitely happening because of the usb keyboard (with
integrated mouse), if I take it out and replace with a ps/2 counterpart
the computer boots up normally.
