Description of problem: Notebook (ThinkPad) doesn't come out of suspend/hibernate with kernel 2.6.18-153.el5 64bit and 32bit are affected Version-Release number of selected component (if applicable): kernel 2.6.18-153.el5 : x86_64 and i686 versions How reproducible: Always Steps to Reproduce: 1. Download and install kernel 2.6.18-153.el5 from http://people.redhat.com/dzickus/el5/ 2a. Suspend through command line or menu 2b. Hibernate through command line or menu 3. Open notebook or press on button 4. Black TFT screen with battery light and suspend light (moon) on Actual results: Doesn't come out of suspend/hibernate Expected results: Come out of suspend/hibernate Additional info: kernel 2.6.18-152.el5 works normally tests are done on a ThinkPad T60 and ThinkPad T43 seems to be related to a CPU#0 soft lockup error
I see a similar problem with a Lenovo Z61t. The machine will suspend to ram sucessfully, but will not recover. When I attempt to hibernate, right after it writes out the memory to disk, I get a panic (or possibly it is a softlockup and it scrolls off the screen). When the failure occurs the suspend indicator light on the laptop is blinking and it doesn't look like kdump will work to capture the dump. I did get a picture of the call trace which I will attach here.
Created attachment 348323 [details] panic at end of hibernate.
The -154 kernel has resolved the suspend/hibernate issues for me. Can you try the -154 kernel to see if it resolves your issues? It is now available at: http://people.redhat.com/dzickus/el5/154.el5/
Tested kernel 2.6.18-154.el5 on both my systems, ThinkPad T43 32bit and ThinkPad T60 64bit, they are suspending and hibernating back as usual. Thank you.
