When booting a 3.1.0-rc10 kernel, right at the start I get an error message printed to the screen: [drm:radeon_dp_i2c_aux_ch] *ERROR* aux i2c too many retries, giving up It's a quad core computer and it prints it 4 times. On another computer which is a dual core it prints the message twice. Both computers have Radeon graphics cards which need firmware compiled into the kernel to work. This computer uses BARTS_mc.bin, BARTS_me.bin, BARTS_pfp.bin and BTC_rlc.bin. The kitchen computer uses REDWOOD_rlc.bin, REDWOOD_pfp.bin and REDWOOD_me.bin. Both computers seem to be working fine as far as I can see. Is this error message something to be concerned about? I thought the radeon driver uses i2c to enable sensors to report the temperature of the card, but that seems to be working fine. I boot with the quite command line argument and it gets rid of most kernel output, but not these error messages. Is there some way I can get rid of these alarming messages? Some kernel option that will make them just complain to the kernel log? Or is there some option I should enable to keep the radeon i2c whatever it is happy? Andy
