On the surface this doesn't sound like anything coreboot or SeaBIOS specific. Can you grab the cbmem console logs on the boot after the power off (cbmem -c)? There is also an eventlog sitting in memory as well that can be grabbed. mosys (https://chromium.googlesource.com/chromiumos%2Fplatform%2Fmosys/+/refs%2Fheads%2Fmaster) should be able to do that work for you: mosys eventlog list The last thing to get is the EC console log. That's much harder to get as you have a kernel that doesn't have the EC driver in it. If you feel adventurous the tool (util/ectool) can be found here: https://chromium.googlesource.com/chromiumos%2Fplatform%2Fec/+/refs%2Fheads%2Fmaster Hope that helps. -Aaron -- coreboot mailing list: coreboot@coreboot.org http://www.coreboot.org/mailman/listinfo/coreboot
