Hi, I think radeon is behaving badly after suspend-to-disk=>resume. Before doing that, it does not show up on the Powertop list. After resuming, it's doing (nearly) constant 50 wakeups/sec.
Is there something I'm overlooking? Or is this fixed already? If not, what would be the right place to continue this discussion (if not here)? This is an IBM Thinkpad T41 with ATI Radeon RV250 [Mobility FireGL 9000]. Kernel 2.6.23, Hrtimers patches. Kubuntu Gutsy, X version 1.3.0. Here's what I did: - Booted on battery. - "rmmod ehci_hcd uhci_hcd e1000 ipw2200" as they all seemed to share interrupt with radeon - Pressed a key when Powertop offered to fix a problem until there were none. - Now Powertop shows this: Cn Avg residency P-states (frequencies) C0 (cpu running) ( 0.9%) 1200 Mhz 0.0% C1 0.0ms ( 0.0%) 1000 Mhz 0.0% C2 0.7ms ( 0.0%) 800 Mhz 0.0% C3 0.6ms ( 0.0%) 600 Mhz 100.0% C4 62.6ms (99.0%) Wakeups-from-idle per second : 16.4 interval: 5.0s Power usage (ACPI estimate): 10.6W (1.0 hours) Top causes for wakeups: 37.2% ( 6.4) artsd : schedule_timeout (process_timeout) 7.0% ( 1.2) kwin : schedule_timeout (process_timeout) 7.0% ( 1.2) kdesktop : schedule_timeout (process_timeout) 5.8% ( 1.0) Xorg : do_setitimer (it_real_fn) 5.8% ( 1.0) klipper : schedule_timeout (process_timeout) 5.8% ( 1.0) artsd : do_setitimer (it_real_fn) 5.8% ( 1.0) dhcdbd : schedule_timeout (process_timeout) - Then I suspended to disk and resumed. - I did "/etc/init.d/laptop-mode restart" as it seems that is not done automatically - Now Powertop shows this: Cn Avg residency P-states (frequencies) C0 (cpu running) ( 1.2%) 1200 Mhz 0.0% C1 0.0ms ( 0.0%) 1000 Mhz 0.0% C2 16.6ms (86.1%) 800 Mhz 0.0% C3 0.1ms ( 0.0%) 600 Mhz 100.0% C4 7.1ms (12.7%) Wakeups-from-idle per second : 70.4 interval: 5.0s Power usage (ACPI estimate): 11.8W (0.8 hours) Top causes for wakeups: 71.5% ( 50.2) <interrupt> : [EMAIL PROTECTED]:0000:01:00.0 9.1% ( 6.4) artsd : schedule_timeout (process_timeout) 6.0% ( 4.2) <interrupt> : acpi 2.0% ( 1.4) kwin : schedule_timeout (process_timeout) 1.4% ( 1.0) Xorg : do_setitimer (it_real_fn) 1.4% ( 1.0) dhcdbd : schedule_timeout (process_timeout) 1.4% ( 1.0) artsd : do_setitimer (it_real_fn) - There's Radeon there at the top. => ??? _______________________________________________ Discuss mailing list [email protected] http://mail.lesswatts.org/mailman/listinfo/discuss
