cras and powerd start chewing CPU on resume from sleep |
||||||||||||||||||||||
Issue descriptionChrome Version: 57.0.2951.0 dev (64-bit) OS: ChromeOS Panther What steps will reproduce the problem? Not sure; I happen to have Google Play Music open in a tab (paused at the time I let the device sleep) and a Chrome Remote Desktop session to a Windows box (which remotes audio). (1) Allow ChromeOS device to sleep. (2) Wake ChromeOS device and unlock. What is the expected result? Expect that device resumes and operates normally. What happens instead? Device is very janky (e.g. text typed into a tab takes several seconds to appear) and top shows cras and powerd processes, and sometimes rsyslogd or kswapd, consuming a lot of CPU.

Issue appears to trigger if I do something I/O intensive, e.g. open chrome://system while audio is playing.

how much is "a lot"? Can you link a feedback report? That will have a reason for both powerd and cras wakeups. Thanks!

Re #3: Yup, I have already filed a feedback report, including this bug # in the description text. Re "a lot", the CPU usage was 80%+, and sufficient to make the mouse cursor stop moving at times, and to cause text to take several seconds to enter.

syslog filled with recover device and metrics failures? Will the recent changes to fix the device resetting fix this too?
