[ 3.097614] [drm] radeon: irq initialized. On recent kernels (3.16 through 3.18-rc4, perhaps), doing anything graphics intensive seems to cause my system to become unusable for tens of seconds. Pointing Firefox at Google Maps is a big offender -- it can take several minutes for me to move my mouse far enough to close the tab and get my computer back. On bootup, I get this warning: [drm:btc_dpm_set_power_state] *ERROR* rv770_restrict_performance_levels_before_switch failed Setting radeon.dpm=0 seems to work around this problem at the cost of giving my rather slow graphics. Are there known issues here?
Can you bisect the kernel, or at least isolate which kernel version first introduced the problem?
