Does booting with nopat (on your kernel command line) help? 2.6.29 needs the firmware to exist as a separate file. Are you sure you installed the firmare package for your distribution ?

I press the Command "dmesg | grep drm" in my system ,and it shows me some ERROR infomation like this: [**ERROR** could not find ioremap agp regions!] How can I fix this problem complete? Could I use the "nopat" kernel option permanently? Dose this kernel option affect my system normal running? (In reply to comment #9) > > thanks for your patient.
