Hi Beeblebrox,

thanks for your report.

You're doing it right, but your hardware has some quirks which can only
be handled by flashrom 0.9.7 or later.

This is very interesting. It might be related to AMD IMC, but I'm not sure.

Could you please retry with flashrom 0.9.7, preferably just reading the
flash chip and producing a log file? See below for instructions.

It would be great if you could run the following command with flashrom
0.9.7.
flashrom -p internal --output readlog.txt -r backup.bin

Then please send readlog.txt to this mailing list. I hope to get further
insight from this.
