Hi All, As documented in 2005 in Documentation/networking/README.ipw2200, "The LED code has been reported to hang some systems when running ifconfig and is therefore disabled by default." We've however been carrying the following patch in our Ubuntu kernel for quite some time which enables the ipw2200 LED by default. This was a result of numerous user requests. We've seen no subsequent bug reports of systems hanging due to the the LED code being enabled by default. I'd therefore like to propose the following patch to enable the LED by default. This patch was originally authored by TJ. I apologize in advance that I do not have TJ's full first and last name for provenance. Thanks, Leann >From 315246037a0edab4d626de6ccb68c73d3fe61ce3 Mon Sep 17 00:00:00 2001 From: ubuntu@xxxxxxxxxxx <ubuntu@xxxxxxxxxxx> Date: Mon, 23 Mar 2009 20:29:28 +0000 Subject: [PATCH] ipw2200: Enable LED by default BugLink: http://bugs.launchpad.net/bugs/21367 Enable LED by default and update the MODULE_PARM_DESC. The original reason for defaulting to disabled was documented in 2005 and noted, "The LED code has been reported to hang some systems when running ifconfig and is therefore disabled by default." This no longer appears applicable and users have been requesting this be enabled for several years.
