From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dirk Behme Subject: Framebuffer driver broken on OSK Date: Tue, 04 Jul 2006 17:04:49 +0200 Message-ID: <44AA8391.7010708@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: linux-omap-open-source-bounces@linux.omap.com Errors-To: linux-omap-open-source-bounces@linux.omap.com To: linux-omap-open-source@linux.omap.com, imre.deak@solidboot.com List-Id: linux-omap@vger.kernel.org Hi, seems that framebuffer on OSK from recent git has some more trouble (not only the missing parameter from my last mail): It crashes completely on OSK. Backlight of LCD is enabled, but then: See log below (low level debugging enabled, without no messages). Any ideas? Best regards Dirk ... <6>io scheduler anticipatory registered (default) <6>omapfb: configured for panel osk <6>omapfb: LCDC initialized <4>omapfb omapfb: Pixel clock divider value is obsolete.
