Subject: usb-ohci preventing reboot on Cobalt Raq550


I'm having a problem with the usb-ohci module under the 2.4.18 kernel
running on Cobalt Raq 550's - if the module is loaded then the machine
doesn't reboot. "shutdown -r now" shuts everything down as usual, the
kernel displays "Restarting system." on the console, but then it just sits
there. If I rmmod the module before shutting down then it does exactly
the same, but after the "Restarting system." message it does actually
reboot.
Has anyone come across this before? I really don't know what to look for
in the ohci driver code that would prevent the system from rebooting, so
any help would be appreciated. Thanks.

Does 2.4.19 show the same behavior?
