What does dmesg say for you? Is it similar to the one from Sean (https://bugs.edge.launchpad.net/ubuntu/+source/acpi-support/+bug/15372/comments/7) - I'm adding it also to the bug description, so it can get found easier.
** Description changed: With a default install of ubuntu hoary after turning on acpi suspend support resuming from S3 causes huge problems. After the machine resumes (the suspending seems to go fine) there is a huge amount of hard drive activity, many application refuse to start (such as top and ls) and the machine tends to freeze completely if I try to open the applications menu. Changing any of the options in /etc/default/acpi-support has no effect and neither does bypassing the scripts in /etc/acpi by echoing mem to /sys/acpi/state manually. I've also tried turning off laptop-mode. I've just come from debian unstable to ubuntu and the debian kernels 2.6.9, 2.6.10 and 2.6.11 did not have this problem. I'm going to try a vanilla kernel from kernel.org to see if that has any effect. I managed to get top running after resuming by starting before I suspended but it didn't really show anything unusual though dd was running and i'm not sure why.

Now X starts and i get back to my desktop but the hard drive still goes crazy. I've tested suspending on a console to see what dmesg had to say after i tried to use ls.
