Subject: [ 88.628451] BUG: unable to handle kernel paging request at f8dbf000 "isight_firmware"

Yesterday I compiled the isight_firmware module, and was happy with
the result's, "no more udev",
This morning I wasn't so lucky, upon a cold boot my system was stuck
during boot, I tried numerous boot's but still the same results,
luckily I was hoping to gather the info on what was going on here it is:

like I said yesterday there was no problem at all, maybe because the
system was warm from being on all day.
after renaming isight_firmware.ko so I can boot up the system runs fine.
hope this helps in the kernel development.
