** Description changed: Resume from suspend (to RAM) doesn't work (powers off instead on resume, didn't touch the power button) for Acer Aspire 3810T and Acer Travelmate 8371/8471/8571 Timeline (and maybe more). WORKAROUND: Add the i8042.reset=1 kernel parameter in GRUB. To do this, change the GRUB_CMDLINE_LINUX_DEFAULT line in /etc/default/grub to look like GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.reset=1" and execute "sudo update-grub" + + Seems to working for (probably for other variations too) : + Acer Aspire 3810T / 3810TG/3810TZ + Acer Travelmate 8371G / 8371 / 8471 + Acer Aspire 3410T Core 2 Solo (or Duo, both have this problem) ULV, Mobile Intel® GS45 Express Chipset, Intel Wifi 5100. 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? Thanks!
