kernel oops after resume from suspened

[Mohmed El Sayed]

I recently upgraded from ubuntu 8.04 to 8.10. One of the reasons I did so to avoid some issues in suspend/hibernate.

I am using Dell inspiron 1525. My current kernel version is 2.6.27-11-generic.

After suspend I got this in /var/log/messages

Hi Mohmed,

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 5.276 seconds. I'm setting this to traiged for further investigation. Thanks!

This is a false positive trigger as the resume was a little slower than we might have liked. Nothing serious occured. Upstream has upped the limit recently and we will now be following suit. This is a duplicate of the bug #464552:
