I can confirm this bug, I was having the same problem since 8.10 and it persisted into 9.04.
Fortunately, I found a workaround for it. If you use the kernel parameter pci=nomsi, you should stop getting those errors. Another parameter I'm using is i8042.reset, it fixes another problem where the keyboard sometimes isn't detected after a successful resume. But after fixing this, another problem remains. The kernel included in 9.04 (2.6.28) has a suspend bug which causes the suspend behavior to be unreliable. The default suspend method on 9.04 didn't work for me out of the box. I tried using only pm-suspend with uswsusp, and sometimes suspend would work, other times it would resume instantly. Suspecting the NVIDIA driver, I removed nvidia-glx-180 and installed 180.51, but I believe it's unrelated as the suspend still wouldn't work reliably, even when not loading the nvidia module. I read somewhere kernel 2.6.29 fixed a suspend bug 2.6.28 had, so I installed it. After this, suspend works perfectly. To sum it up, the combination that works for my Aspire 4530 is: - Kernel 2.6.29-020629-generic (you can download the debs here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.29/ ) - Kernel parameters pci=nomsi and i8042.reset - Use SUSPEND_METHODS="pm-utils" on /etc/default/acpi-support - Use SLEEP_MODULE="uswsusp" on /etc/pm/config.d/00sleep_module - NVIDIA driver 180.51 (may be irrelevant to this issue; try nvidia-glx-180 from the repositories first) It was hard getting suspend working, but it was worth it. Let me know how it goes for you. -- [Acer, inc.
