Message-ID: <Pine.LNX.4.64.1106171602330.27141@axis700.grange> Date: Fri, 17 Jun 2011 16:08:04 +0200 (CEST) From: Guennadi Liakhovetski <g.liakhovetski@....de> To: Stefano Brivio <stefano.brivio@...imi.it>, Michael Buesch <mb@...sch.de> cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [BUG] b43 / ssb: kernel BUG() in __queue_work() Hi I'm getting reproducibly the below BUG() with recent kernels, e.g., next of today. Occurs on ARM and SuperH with an SDIO b43 card. Using WPA2, configure a network and start ping from outside, within a couple of minutes (usually under 1 minute actually) the kernel crashes.
