I haven't had the chance to test this yet, but could the problem be related to what's described in http://lkml.org/lkml/2007/4/17/41? the cpuidle code referenced there is only in -mm right now, so no, that's unrelated. The flashing keyboard LEDs that you see are an indication that the kernel 'oopsed'. Unfortunatly, getting debug info out of the kernel when it does this is extremely difficult, as not much of the system is 'up' at that stage, so networking, console etc aren't back. I'm debugging a number of other suspend related issues at the moment, so it's possible that at some stage this will get fixed as fallout from that, but without a serial console or similar, there's not much to go on from this bug. have a look at this: http://people.freedesktop.org/~hughsient/quirk/ I have looked at that link. The easy fixes don't seem to help much, so I tried using 'pm_trace' with a patched 2.6.22-rc3 kernel. I had already put iwl3945 into /etc/pm/config.d/unload_modules. Here's the output I got: hash matches drivers/base/power/resume.c:57 This particular problem seems to have been solved. With kernel 2.6.22-8.fc7 the laptop suspends and resumes, though the backlight level is far too dim. The laptop is now running rawhide and the on-resume oops hasn't re-appeared. |
