--- Comment #2 from Alex Deucher <agd5f at yahoo.com> --- Please attach your dmesg output with radeon.dpm=1 set on the kernel command line in grub. That dumps some additional debugging output. Also please attach a copy of your vbios. (as root) (use lspci to get the bus id) cd /sys/bus/pci/devices/<pci bus id> echo 1 > rom cat rom > /tmp/vbios.rom echo 0 > rom -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
