Description of problem: I see a kernel BUG message when doing suspend/resume on my Dell Latitude D810 laptop. This happens only with kernel 2.6.18-1.2200.fc5. I have been using kernel 2.6.17-1.2187_FC5 without any such error. Here is what shows up in my dmesg Stopping tasks: ===========================================================================================================================| Shrinking memory... done (71681 pages freed) pnp: Device 00:0b disabled. eth1: Going into suspend... .............................. swsusp: Need to copy 63769 pages Intel machine check architecture supported.
