When running "sudo flashrom" I gett the following output:
flashrom v0.9.1-r946 No coreboot table found. ======================================================================== WARNING! You seem to be running flashrom on a laptop.

This chipset supports the following protocols: Non-SPI. Calibrating delay loop... OK.

Please include the flashrom output with the additional -V option for all operations you tested (-V, -rV, -wV, -EV), and mention which mainboard or programmer you tested. Thanks for your help! === No operations were specified.
After this the keyboard and touchpad stops working. Also one of the thermal sensors stops working too. Plugging in a usb mouse allows me to shut down the laptop nicely tho.

Running "sudo flashrom" once more after reboot will cause the laptop to reboot immediately. Shutting down and removing power cable and battery resets the condition so "sudo flashrom" just disables keyboard/touchpad.
Running "sudo flashrom -r backup.rom" will cause the laptop to shut down immediately.
I read some abut making support for a laptop but it seemed a bit complicated for me.

...this points to a crashed embedded controller.

Because this resets the embedded controller.

If you have a vendor BIOS update, the magic to code needed to have the EC cooperate is included within that update. Do you have a link?

Yeah, this contains enough info to have support for that system in flashrom. Still we would like to have - The ouptut of lspci -vvvnnxxx (run as root) - The output of superiotool -deV (http://www.coreboot.org/Superiotool#Installation) for every system we add support for. Also we need that info to find out how to uniquely identify your system. Please also attach the output of dmidecode, but you might want to blank out UUIDs/serial numbers.

Hi again!
added the output from lspci and superiotool as attachments.

BE WARNED: FLASHROM COMES WITH NO WARRANTY! THIS IS ESPECIALLY TRUE FOR LAPTOPS, AND ESPECIALLY ESPECIALLY TRUE FOR LAPTOPS WITH SHARED EC. Nevertheless, I think that trying to *read* flash contents with this patch is not more unsafe than reading without this patch. Be warned that a crashed EC might mean no fan control. Don't even *THINK* about erase/write until read works fine!
This is the first system with EC sleep support in flashrom, and the first user of the register_shutdown infrastructure.
PCI match uses one out of many chips with subsystem ID Acer:0x0057, and also the northbridge (with bogus subsystem ID). DMI match added just for safety, as fiddling with the KBC is dangerous.
