The bug is that my X60s notebook would not suspend-to-ram on the 2nd try. Boot up -> suspend to ram -> ok -> resume -> suspend to ram -> hang! The hang would only happen while in X. If I don't enter X, it'll not hang on suspend to ram. I tried git bisect but can only get to this commit 4a27214d7be31e122db4102166f49ec15958e8e9. The next commit b82287587ef9917afbea5fcbf7aa63424b6f3719 would not boot. How can I get pass the "bad" commit. I've tried "skip" or "next", but still won't boot. And it doesn't seem like it's X as 2.6.25 kernel can suspend and resume many times in X without problem. Here's how I bisected ... git-bisect start # bad: [b8291ad07a7f3b5b990900f0001198ac23ba893e] Linux 2.6.26-rc3 git-bisect bad b8291ad07a7f3b5b990900f0001198ac23ba893e # good: [4b119e21d0c66c22e8ca03df05d9de623d0eb50f] Linux 2.6.25 git-bisect good 4b119e21d0c66c22e8ca03df05d9de623d0eb50f # good: [c328d54cd4ad120d76284e46dcca6c6cf996154a] Merge git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/v4l-dvb git-bisect good c328d54cd4ad120d76284e46dcca6c6cf996154a # bad: [25a025863e024f6b86b48137b10b4960c50351b0] Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6 git-bisect bad 25a025863e024f6b86b48137b10b4960c50351b0 # bad: [62d9f0dbc92d7e398fde53fc6021338393522e68] KVM: add ioctls to save/store mpstate git-bisect bad 62d9f0dbc92d7e398fde53fc6021338393522e68 # good: [ce1d5b23a8d1e19866ab82bdec0dc41fde5273d8] Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input git-bisect good ce1d5b23a8d1e19866ab82bdec0dc41fde5273d8 # good: [a2826190aa157a1d29bef70ca81f8b51a9b36d29] IDE: Coding Style fixes to drivers/ide/pci/it8213.c git-bisect good a2826190aa157a1d29bef70ca81f8b51a9b36d29 # bad: [9b79ed952bd7344d40152f8a560ad8a0d93f3886] Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-generic-bitops-v3 git-bisect bad 9b79ed952bd7344d40152f8a560ad8a0d93f3886 # bad: [4a27214d7be31e122db4102166f49ec15958e8e9] Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86-fixes git-bisect bad 4a27214d7be31e122db4102166f49ec15958e8e9 # bad: [b82287587ef9917afbea5fcbf7aa63424b6f3719] Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-x86-misc git-bisect bad b82287587ef9917afbea5fcbf7aa63424b6f3719 Thanks, Jeff.
