--- Comment #15 from Stuart Foster smf.linux@ntlworld.com --- Created attachment 108661 --> https://bugzilla.kernel.org/attachment.cgi?id=108661&action=edit Output from dmesg from vanilla kernel 3.12-rc1

With the release of kernel 3.12-rc1 I took the opportunity look at the display stability of the kernel with non of the patches we discussed applied and I was surprised to see that the display was unexpectedly stable. However I am wondering if dpm is actually active for some reason and masking my original issue. The following extracts from the attached dmesg log are what give me grounds for concern:
Kernel command line: BOOT_IMAGE=Trial ro root=813 nf_conntrack.acct=1 userpte=nohigh radeon.modeset=1 radeon.agpmode=-1 radeon.audio=1 iommu=pt iommu=1 radeon.dpm=1 Booting kernel: `-1' invalid for parameter `radeon.agpmode'
[drm] radeon: power management initialized
what do you think ?
