7.0 RC2 usb problems

[Paul Schmehl]

I just installed 7.0 RC2 on a brand new Dell - dual processor dual core Intel 
(so four processors), and I'm losing the keyboard and mouse after taking 
certain actions.  For example, I started setting up X (Xorg --configure) and 
then launched it (X -config /root/xorg.conf-new), and when I get to the GUI the 
mouse and keyboard are gone.  Sometimes I can restore functionality by 
unplugging the devices and then plugging them back in.  This is happening in 
the console as well, not just in the GUI.

I've fetched the latest sources using cvsup.  Will rebuilding the kernel solve 
this problem?  Is this a known issue?

usbhidctl shows ums0, ums1, ukbd0 and ukbd1 to be busy.

[root at utd65257 ~]# usbhidctl -a -f /dev/ums0
usbhidctl: /dev/ums0: Device busy
[root at utd65257 ~]# usbhidctl -a -f /dev/ums1
usbhidctl: /dev/ums1: Device busy
[root at utd65257 ~]# usbhidctl -a -f /dev/ukbd
ukbd0  ukbd1
[root at utd65257 ~]# usbhidctl -a -f /dev/ukbd0
usbhidctl: /dev/ukbd0: Device busy
[root at utd65257 ~]# usbhidctl -a -f /dev/ukbd1
usbhidctl: /dev/ukbd1: Device busy

This is what I see after unplugging both devices and plugging them in to 
different usb receptacles.
