Sometimes when booting 2.5.40 and my Freecom USB-IDE controller (CDRW) is connected, the kernel panics when trying to initialize the usb subsystem. It happens right after the RH73 boot scripts print out:
Initializing USB controller (uhci-hcd): [ OK ]
In 2.5.39, this happened every time I tried to boot, but in 2.5.40 it seems to happen about 20% of the time.
