Ibex Peak hangs

[John]

Here is my lspci: http://flashrom.pastebin.com/4zVD3z7S

When attempting to read, the chipset is not detected. After editing
chipset_enable.c, changing the "3b00" in '{0x8086, 0x3b02, NT, "Intel",
"3400 Desktop",   enable_flash_ich10}' to "3b02", the following is
output, followed immediately by a hard freeze:
http://flashrom.pastebin.com/jNBdZ4YC

"sudo ./flashrom -VV -c SST25VF016B" output:
http://flashrom.pastebin.com/UA4vBm52

After applying this patch: http://patchwork.coreboot.org/patch/1532/
the output of "sudo ./flashrom -VV -c SST25VF016B" is:
http://flashrom.pastebin.com/rCEgShPk

And the output of "sudo ./flashrom -VV" was another freeze and output
identical to:
http://flashrom.pastebin.com/jNBdZ4YC

Carldani said to mention that "flashrom hangs the machine on RES/REMS
probe after you add an ich10 chipset enable for PCI ID 8086:3b02".

Hi John,

it seems this Ibex Peak hang is fixed in latest flashrom from svn. Could
you please retry?

Thanks for the update. I pulled the latest from svn, did 'make clean'
and 'make', and then ran "sudo ./flashrom -Vr" with the following
output. Does this help?

Thanks for retesting. The results are very helpful.

Great, the hang is now fixed.
Reading fails, but that is caused by a forbidden region:

0x5C: 0x003f0003 (FREG2: Management Engine)
0x00003000-0x0003ffff is locked

I've reposted your log to http://paste.flashrom.org/view.php?id=218
where we run some analysis on old logs from time to time.
