Description Mathieu Malaterre 2015-05-26 08:45:02 UTC
On my old Mac Mini G4 (PowerPC) I am seeing this dmesg output:

It would be nice to either remove this error report as I believe it is erroneous.

Using debian/jessie with:

$ apt-cache policy libdrm-radeon1
libdrm-radeon1:
  Installé : 2.4.58-2
  Candidat : 2.4.58-2
 Table de version :

Hi,

actually the "error report" is correct, on PPC platforms there is no BIOS but the hardware is configured via Open Firmware. I've been getting this message for years, it's totally harmless.

By the way: Do you have AGP mode working stable on the Mac Mini G4 ? I've been trying to do that for years with no success :-(

Ok. Closing as invalid then.
