Warning after laptop went to sleep (suspended)

[willix71]

Closed the lid on my HP Pavilion dv7 2150ez, it went to sleep!
Opened the lid, the laptop is working but I had a warning saying the kernel might be unstable and I should reboot (which is kind of the opposite of what you want of a sleep option :(
The brightness of the screen was also reduced to the minimum...

Same here, on a Dell Latitude D620 with Core 2 (T2500) after a fresh Karmic install (CPU frequency scaling finally works!)

Hi willix71,

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 5.256 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!
