Red Hat Bugzilla – Bug 439669
100% CPU Usage
Last modified: 2009-07-14 12:04:42 EDT
Description of problem: hald-addon-input is consuming 100% on my ThinkPad X41T tablet PC. The laptop includes a Wacom Serial Tablet PC Stylus, a Trackpoint, and a keyboard (but no trackpad). ps and /proc/<pid>/cmdline return the command line as: "hald-addon-input: Listening on /dev/input/event3 /dev/input/event4 /dev/input/event5 /dev/input/event1 /dev/input/event7" (with the ':' and everything) Attaching to the process with strace shows a tight poll loop: poll([{fd=4, events=POLLIN}, {fd=5, events=POLLIN}, {fd=6, events=POLLIN}, {fd=8, events=POLLIN}, {fd=9, events=POLLIN, revents=POLLNVAL}, {fd=3, events=POLLIN}, {fd=7, events=POLLIN}], 7, -1) = 1 (note the POLLNVAL for fd=9) ls /proc/<pid>/fd only lists fd's 0..8 Version-Release number of selected component (if applicable): hal-0.5.11-0.2.rc2.fc9.i386 How reproducible: Always Steps to Reproduce: 1.Start X 2.Run top Actual results: 100% CPU usage. Laptop almost, but not quite, hot enough to fry eggs. Expected results: No coagulation of eggs. Additional info: Just upgraded to Rawhide using yum on March 30th from an up-to-date and perfectly working Fedora 8 installation.
The problem seems to be caused by the thinkfinger (fingerprint reader) Removing thinkfinger-0.3-8.fc9.i386 temporarily mitigates the problem.
Changing version to '9' as part of upcoming Fedora 9 GA. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
This message is a reminder that Fedora 9 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 9. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '9'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 9's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 9 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 9 changed to end-of-life (EOL) status on 2009-07-10. Fedora 9 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
