I have a new acer chromebook I have flashed with coreboot + seabios payload. It boots to linux ok, but then powers off suddenly after 30 min regardless of whether I am using it.
I disabled hibernation and have been leaving it plugged in, but this changes nothing. I suspect a faulty intel me since there is nothing else I can think of. The strange thing is I did not use me cleaner but used the full me extracted from the original bios. Later I downloaded the stock chrombook bios for my model from google and extracted the me module from that.
At this point I have built several variations of roms using the me module from the original bios, the google bios, and "cleaned" versions of both but always with the same problem of power off after 30 min.
I am confused as to what the problem may be. I used the intelmetool bundled with coreboot but when I run it with the -s flag it seg faults.
In order to extract the me rom I used ifdtool that is included with coreboot. ./ifdtool -x bios.bin The intel me module is found at offset 00001000 - 001fffff and is 2 mb in size. Is that the correct way to do it?
Any suggestions would be appreciated.
The ME state is logged in the coreboot console. You can read it with `cbmem -c` (see util/cbmem/ in the coreboot source tree). If you set the default log level high enough, you should find some lines starting with "ME:".
Hope that helps, Nico
