--- Comment #19 from Henrique de Moraes Holschuh <h...@hmh.eng.br> 2009-05-08 00:58:02 --- Well, nowadays, this report is about the power resources not working, and not being easily fixed. It is about more than they not being disabled :( First, we were not registering all power resources that we should as "referenced by an active device". This is PROBLEM-1. My patch fixes this, but it exposes other problems. We are not turning devices off, and therefore we are not releasing power resources. This is PROBLEM-2. We can't always turn devices off, so the fix for this is not simply to always turn devices off. We are not detaching power resources when a module is unloaded (because of PROBLEM-2). This leaves dangling pointers in linked lists, and is PROBLEM-3. We can't fix PROBLEM-1 without fixing PROBLEM-3, because it will trigger PROBLEM-3 in every ThinkPad produced in the last five years. We are not checking for power resources that are to be turned off before sleep. This is PROBLEM-4, and fixed by a revert of ff24ba74b6d3befbfbafa142582211b5a6095d45, but we can only do this after we fix PROBLEM-1 (or we will regress on ThinkPads). We are not doing opportune scans to find power resources that could be turned off. This is PROBLEM-5, and just like PROBLEM-4, it can only be fixed after we fix PROBLEM-1 (or we will regress on ThinkPads). So, PROBLEM-2 is the key. It needs to be fixed first. I don't know how we can fix it. -- 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. ------------------------------------------------------------------------------ The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
