Most recent kernel where this bug did *NOT* occur: 2.6.20-rc7 Distribution: Debian Testing Hardware Environment: Acer TravelMate 242 Software Environment: Problem Description: Some "patch" between 2.6.20-rc7 and 2.6.20-final-vanilla has broken my SWSUSP resume. In 2.6.20-rc7 kernel after image load from disk normally wake up into my Xorg and everythink is fine, but in 2.6.20-final after disk image load starts Capslock blinks - kernel freezes :( Steps to reproduce: Boot both kernels on the laptop
Created attachment 10284 [details] kernel config config 2.6.20 - same used for 2.6.20-rc7
Hm, there are not a lot of patches between -rc7 and 2.6.20. Can you perhaps try to find the offending one among them?
Yup I would like find it this way, but compile 25x kernel is too much, maybe we can make it smaller before research.
Not 25, more like 6 with git bisecting: # install git and cogito on your computer # clone Linus' tree: cg-clone \ git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git # start bisecting: cd linux-2.6 cp /path/to/.config . git bisect start git bisect bad v2.6.20 git bisect good v2.6.20-rc7 # start round make # install kernel, check whether it's good or bad, then: git bisect [bad|good] # start next round After at about 6 kernels, you'll have found the guilty commit ("... is first bad commit"). More information on git bisecting: man git-bisect
Fixed in 2.6.21 - swsusp/resume works again
