Hi,

When I plug my USB IR receiver (MCE) in, I get the error and trace 
messages hereby attached.  It doesn't freeze the system but when I try 
to boot the machine with the USB receiver plugged in, it actually 
prevents the system to boot entirely.  I've configured a 2.6.39.4 kernel 
with those drivers built-in,
	CONFIG_RC_MAP=y
	CONFIG_IR_RC6_DECODER
	CONFIG_IR_MCEUSB=y

I'm basically using the default configuration + EXT4 + BRIDGE + NTFS + 
NFSD + FUSE + DRM_RADEON & firmware, nothing funky (and cpu family opteron).

Here's the error I got in brief (from dmesg),

mceusb 3-2:1.0: usb_probe_interface

Some help will be greately appreciated.
