I tried something else. I removed the write and only added a printk with a register read to print the contents (DDC REG IS 0x...) . This is the result: [ 0.431304] PCI: Enabling device 0000:00:10.0 (0006 -> 0007) [ 0.626866] radeonfb (0000:00:10.0): Invalid ROM signature 303 should be 0xaa55 [ 0.626877] radeonfb: Retrieved PLL infos from Open Firmware [ 0.626887] radeonfb: Reference=27.00 MHz (RefDiv=12) Memory=203.00 Mhz, System=392.00 MHz [ 0.626897] radeonfb: PLL min 12000 max 35000 [ 0.627194] DDC REG IS 0x00000303 [ 0.763751] i2c-adapter i2c-2: unable to read EDID block.

Note that the function is called twice. Is that correct? -- Greetings Michael. _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
