From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.10) Gecko/20050719 Fedora/1.7.10-1.5.1 Description of problem: After upgrading to kernel-2.6.12-1.1447_FC4, I now see the following messages in my syslog: Driver for 1-wire Dallas network protocol. matrox_w1 0000:01:00.0: Matrox G400 GPIO transport layer for 1-wire. w1_driver w1_bus_master1: No devices present on the wire. w1_driver w1_bus_master1: No devices present on the wire. w1_driver w1_bus_master1: No devices present on the wire. .... Series of the 'w1_driver' messages continue to appear at regular intervals (every minute or so). To stop them, I can 'rmmod matrox_w1' (as some initial research indicated) and then I see a few messages as below: Aug 31 19:28:34 localhost kernel: Waiting for w1_bus_master1 to become free: refcnt=2. Aug 31 19:28:35 localhost kernel: Waiting for w1_bus_master1 to become free: refcnt=1. Aug 31 19:28:43 localhost last message repeated 8 times And then they do indeed stop. I've heard that this module is loaded automatically when a Matrox card is detected (I have a G450). The question is why and why it generates so many syslog messages. Version-Release number of selected component (if applicable): kernel-2.6.12-1.1447_FC4 How reproducible: Always Steps to Reproduce: 1. Reboot 2. Watch the syslog Actual Results: Syslog was spammed every minutes by the above messages. Expected Results: The messages should not appear (and, arguably as I don't know it's function, the matrox_w1 module should not be loaded). Additional info:
This is still a problem in 2.6.12-1.1456_FC4 but I've simply disabled the matrox_w1 module in /etc/modprobe.conf for now.
From User-Agent: XML-RPC kernel-2.6.13-1.1526_FC4 has been pushed for FC4, which should resolve this issue. If these problems are still present in this version, then please make note of it in this bug report.
