WARNING: at /build/buildd/linux-2.6.38/kernel/power/suspend_test.c:53 suspend_test_finish+0x86/0x90()

[Steve Magoun]

Upon resuming from suspend I got a dialog warning me of a Serious Kernel Problem. The dialog prompted me to file this bug. Apart from that warning, the system seems to be functioning normally.

I assume the Serious Kernel Problem is really the following in dmesg, this machine is indeed a little slow to wake from suspend:

The battery device seems to be the culprit, note the jump from 1944ms to 17279ms:

Hi Steve,

The warning reported here typically indicates that it took longer for your system to resume from suspend than expected. I believe there is a 5 sec barrier which your system likely exceeded. Based on your dmesg output I see PM: resume devices took 1.490 seconds. A patch to prevent this warning has been applied via bug 464552. As a result I'm marking this as a duplicate to bug 464552. Please continue to track this issue at that report. Thanks!
