Ok yes I was running the most current kernel on fedora core 11. I also
upgraded from fedora core 10 to 11. 

 

I figured it was a bug and also got in a hurry and I figured I would need to
go FC12 eventually so I went ahead and upgraded to FC12 

The new problem is displayed below 

 

lirc_dev: IR Remote Control driver registered, major 249

lirc_i2c: chip 0x10020 found @ 0x18 (Hauppauge IR)

i2c ir driver 1-0018: lirc_dev: driver lirc_i2c registered at minor = 0

lirc_serial: auto-detected active high receiver

BUG: unable to handle kernel NULL pointer dereference at 0000000000000010
