I'm using Ubuntu 10.10 64-bit on my acer 5735z kernel: 2.6.35-26-generic (from Ubuntu repos)
Now I'm booting with pci=noacpi, the problem still occurs but with less frequency (i think..). Using acpi=off solves the problem. I don't know when this issue appears, I can't even reproduce that bug. I suddenly can't adjust my screen brightness and there are a lot of messages in dmesg. [20135.512530] ACPI: EC: input buffer is not empty, aborting transaction [20135.512539] ACPI Exception: AE_TIME, Returned by Handler for [EmbeddedControl] (20100428/evregion-474) [20135.512555] ACPI Error (psparse-0537): Method parse/execution failed [\_SB_.AMW0.WMCA] (Node ffff8800b7a34500), AE_TIME After I poweroff (when adjusting brightness doesn't work) my laptop won't boot. Lights goes up for a few seconds and off (and it loops), I can't get into BIOS. I have to take out battery and remove power for a few seconds, then I can boot my laptop. That is all I know about it. Hope it will help.
