> It took me some time to write down all this lines using this method,
this machine doesn't have a serial port.
Sorry, I totally forgot to mention that the matching
add_memory_type_range()/remove_memory_type_range() pairs can be omitted.
> I wish it would be possible to dump this syslog to usb flash, sigh.
Yeah, that would be nice. Unfortunately writing to a file system on disk
is not so simple in the boot loader. Maybe at least FAT32 support can be
added.
> Anyway, please look at the attached MTRR_output.txt.
Thanks! I'm not quite sure why it ends in garbage. Maybe the data had not
yet been written from the CPU cache back to memory when the reset
happened. I haven't encountered that in my tests. How did you reset the
machine?
Anyway, the syslog does at least suggest that there are several very small
RAM ranges which complicate the MTRR setup significantly. As of r35825
those will simply be ignored. Please give it a try. Even if it works
please add a fresh syslog for reference.
