------- Comment #20 from h...@hmh.eng.br 2009-03-18 15:46 ------- That patch is no good then. Well, I have (probably) fixed it in a very different way. I removed mode 3, wrote a new mode 3 that does only ec control (like mode 1, which we know to work well from your reports) but stores the end result in NVRAM on shutdown. I have switched every thinkpad that knows what the EC backlight brightness register is to the new mode 3 by default, and all others to mode 2 (UCMS/CMOS). That should fix it, as it simply removes any races with the firmware in mode 3 (they might clobber each other, but they won't race). UCMS is probably race-free, since it is atomic (uses SMM). It is a big patch, it doesn't make sense to add it to this bug report and it requires a few other patches not in mainline yet. Instead, I will release soon a new BETA version of thinkpad-acpi through ibm-acpi.sf.net, and request testers and reports in the linux-thinkpad ML. After it gets some field testing, I will send it to mainline (probably for 2.6.31, since I doubt I will have enough reports to have it ready for the 2.6.30 merge window). -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is. ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
