Oops on /dev/fb0
Hello,
I'm running debian stable on a Sun Ultra 5. Everything is running
fine, but if I do a simple `cat /dev/fb0' I get an kernel oops.
This happens with the debian kernel 2.4.18, and the same with 2.6.1. Any
ideas what is going on? Or should I report this at
http://bugzilla.kernel.org/?
