Works for me as well. This is unbelievable! I already thought this to be unsolvable in kernel, but this did it! Thanks!
I edited the original description so the workaround is easier to find. ** Description changed: Resume from suspend (to RAM) doesn't work (powers off instead on resume, - didn't touch the power button) for Acer Timeline 3810t (and friends). + didn't touch the power button) for Acer Aspire 3810T and Acer Travelmate + 8371/8471/8571 Timeline (and maybe more). - http://www.acer.co.uk/acer/seu30e.do?LanguageISOCtxParam=en&link=ln374e&CountryISOCtxParam=UK&acond125e=58846&kcond48e.c2att101=58846&sp=page17e&ctx1g.c2att92=122&ctx2.c2att1=17&ctx1.att21k=1&CRC=821813855 + WORKAROUND: Add the i8042.reset=1 kernel parameter in GRUB.

I have tried 9.04, 9.10 alpha 2 and 3, kernels 2.6.28 to 2.6.31, all 32-bit. BIOSes 1.04 and 1.08 (latest). Nothing works. There is a single isolated report of suspend working with 64-bit 2.6.30. https://help.ubuntu.com/community/AspireTimeline/Fixes Suspend seems to work perfectly, but when a key is pressed to start resuming, the machine seems to start back up, but automatically powers off afer a few seconds (screen didn't come back up). Using the "resume-trace" procedure described here does not yield any matches. Unloading all non-essential modules in single user mode doesn't fix it (used /etc/acpi/sleep.sh to initiate suspend). Suspend is initiated through gnome-power-manager, but I don't think that's the problem. What else can I try?
