Wysocki" Content-Type: text/plain; charset=UTF-8 Date: Tue, 10 Jun 2008 14:38:21 +0200 Message-Id: <1213101501.21041.9.camel@pern> Mime-Version: 1.0 X-Mailer: Evolution 2.22.2 Content-Transfer-Encoding: 8bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org I just opened this: http://bugzilla.kernel.org/show_bug.cgi?id=10892 . I think itś a regression, but (read the description) I am not so sure, so I checked regression but I have not blocked Rafael's metabug. Latest working kernel version: 2.6.25 Earliest failing kernel version: After 2.6.25, exatcly don't know, probably 2.6.26-rc3 Distribution:Ubuntu 8.04 Hardy Hardware Environment: toshiba U305 intel-based laptop, see http://bugzilla.kernel.org/attachment.cgi?id=16067&action=view Software Environment:xserver-xorg-video-intel 2:2.2.1-1ubuntu12, see also http://bugzilla.kernel.org/attachment.cgi?id=16066&action=view Problem Description: Sometime, on cold boot (after the laptop has been shut off), when the screen switch from the Ubuntu startup to gdm, the screen goes blank. Forever. Rebooting (warm) with the same kernel cures it, sometime. If I reboot 2.6.25 it cures it everytime. Otherwise, the system seems to be working. It was difficult to see because I almost never do a cold boot, the laptop is either sleeping (s2ram) or on, or (warm) rebooted when I test a new kernel. Helps / tricks to gather more data when it happens are welcome. -- Sorry for the disclaimer --- ¡I cannot stop it! -- La presente comunicación tiene carácter confidencial y es para el exclusivo uso del destinatario indicado en la misma.
