Subject: BUG: unable to handle kernel NULL pointer dereference at 00000002

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
mceusb 3-2:1.0: usb_probe_interface - got id
