> Note, ideally we would already filter them at the "kernel" netlink source
That's possible because that android driver doesn't use libudev to get these events, but sets up its own netlink socket. We really don't want to see these events anywhere else. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1234743 Title: omapfb module floods system with udev events on samsung galaxy nexus Status in Upstart: Fix Released Status in “linux” package in Ubuntu: Invalid Status in “lxc-android-config” package in Ubuntu: In Progress Status in “powerd” package in Ubuntu: Fix Released Status in “systemd” package in Ubuntu: In Progress Bug description: Playing an mp4 on a Samsung Galaxy Nexus using today's image (3 Oct 2013) for 30 minutes I observed that init is busy and also consuming heap quite rapidly. Attached is the output from running health-check (found in PPA:colin- king/white) on init pid 1114. Key points: 1. messages being read/written at ~600 messages a second, hence the high context switch rate and ~4.9% CPU load. 2. heap consumption: ~30K a second using brk() and 2K a second via mmap To reproduce: Install health-check: sudo add-apt-repository ppa:colin-king/white sudo apt-get update && sudo apt-get install health-check Download a large mp4 to the phone. Keep screen from blanking using: sudo powerd-cli display on bright & then play the mp4: dbus-launch mediaplayer-app test.mp4 --desktop_file_hint=/usr/share/applications/mediaplayer-app.desktop --stage_hint=main_stage And then observe that init is busy for 300 seconds: ps -e | grep init 1 ? 00:02:56 init 348 ? 00:00:00 init 1114 ? 00:03:22 init sudo health-check -p 1114 -d 300 Attached are my results for a 30 minute run.
