I am trying to get suspend/resume working on Acer Travelmate 230 laptop (with the latest available BIOS for that box). APM on it is fubar, so that option is out. With the latest of Arjan kernels (current Redhat "rawhide", 2.6.6-1.391) I can do that as long as I will boot with 'acpi_sleep=s3_bios' parameter and ehci_hcd module _not_ loaded.
With the above after 'echo 3 > /proc/acpi/sleep' the laptop goes to sleep (any other value but 3 above does not have any discernible effect) and even resumes - mostly. Strictly speaking it does that even without 'acpi_sleep=s3_bios' but then video is totally gone, regardless if X was started at any time or not, so this is not that useful even if its keyboard and a network interface are still operational. :-) The problem is that after a resume its three USB hubs are visible but anything attached is gone. Unloading and reloading uhci_hcd module, which is in use, before or after sleep/resume cycle does not have any effect. Replugging an external device (a mouse in this case) is not doing anything either. Any ideas how to wake up that bus? An internet search so far drew blank. Another thing which is vanishing is a floppy. Its driver can be reloaded without problems but a mechanism itself after a resume is incommunicado. This is something which can be suffered for now. No idea about PCMCIA slot as I do not have at this moment anything to plug in there. But USB is here really important. Oh, with ehci_hcd present a laptop starts a "going to sleep" sequence but immediately wakes up by itself. A sleep indicator LED never even blinks. Please cc to me replies. I am not subscribed.
