Hi Jimmie,

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.
