Created attachment 502436 [details] Trace Description of problem: Sometimes while suspending to ram (mostly the first time after a fresh restart) I get an INFO trace, presumably while the system tries to shutdown the non-boot core of the CPU. Suspending completes however and the system is able to resume afterwards. Version-Release number of selected component (if applicable): 2.6.38.6-27.fc15.x86_64.debug #1 How reproducible: I don't usually suspend to ram, I prefer hibernating instead (which also gives a similar trace, see bug 709544 ( https://bugzilla.redhat.com/show_bug.cgi?id=709544 ). But the few I do, I get it almost every time. Steps to Reproduce: 1. Boot 2. Login 3. Close lid to suspend. Actual results: Trace generated Expected results: No trace Additional info: This is on a Dell Latitude E4300, 6GB RAM, Intel GM45 with an SP9600 CPU. This laptop seems to hang into ACPI ( "ACPI: While loop taking a really long time. loop_count=..." ) after some number of hibernation/thaw cycles and/or throw random oops traces during hibernation/thaw that I was unable to save so far. Hence I run a debug kernel and hope to catch something more in my logs just before that happens. This INFO trace is such a catch.
2.6.38.6 is fairly ancient at this point. If you're still seeing this with the recent F16/F17 debug kernels, please open a new bug with the full trace.
