Comment:
This happens because CONFIG_NONPROMISC_DEVMEM (pre 2008-07),
CONFIG_STRICT_DEVMEM or CONFIG_X86_PAT are set in your kernel.
Although flashrom can do nothing about any of these, I will add this
information to the error message, so I'm not closing the ticket just yet.

There is an entry in the FAQ for this issue [1].

Any change which improves the error message (with an URL or a detailed
explanation (preferred because it is usable if you have no internet
connection)) is

Comment(by lymanrb@…):
I've seen the info you added in source code. However, I didn't get it
printed when I recompile and run.
I debugged a little and found that the error occurred at line 193 of
cbtable.c, the errno is 22. I'm not sure whether this helps.

Hello,
This happens because CONFIG_NONPROMISC_DEVMEM (pre
2008-07),
CONFIG_STRICT_DEVMEM or CONFIG_X86_PAT are set in your kernel.
Although flashrom can do nothing about any of these, I will add this
information to the error message, so I'm not closing the ticket just yet.
I did not try it but this kernel patch may fix the issue with CONFIG_X86_PAT
since flashrom tries to mmap the first MB in cbtable.c:
http://bugzilla.kernel.org/show_bug.cgi?id=12372
Kind regards

Comment(by stuge):
http://bugzilla.kernel.org/show_bug.cgi?id=12372 is possibly related to
CONFIG_X86_PAT being problematic here, but no testing has been made to
verify if that is the case. All test results most welcome. Thanks to Niels
Ole Salscheider for pointing this out.
