Hey, I hope you guys get some use of these, thanks
thanks for your report. It looks like the IMC in your southbridge is stuck and we can only read garbage.
I hope you didn't try to write to this chip. If you tried and it hung/failed, please tell us so we can figure something out.
Could you please check if latest flashrom from svn (at least 0.9.2-r1145) complains about corruption?

Classic case of a stuck FIFO. flashrom 0.9.2-r1145 and later should print loud warnings about corruption and refuse to read/write.
