Dear Coreboot developers,

I installed Coreboot with ThinkPad X60s and Debian 9 and they run
successfully, but I observe a weird behavior.

Even though I had enabled blob for microcode update, the system seems
to run without it. I saw the following message in dmesg:
(I think this is not fatal since this is related to temperature
monitoring, though.)

> coretemp: Errata AE18 not fixed, update BIOS or microcode of the CPU!

For comparison, I had installed `intel-microcode` package to the
system and then the message disappeared.

Is this intended behavior, misconfiguration, or a real bug?

For reference, I uploaded the content of /proc/cpuinfo before and
after the installation of `intel-microcode` package:

Also, I uploaded a report to board-status:
https://review.coreboot.org/cgit/board-status.git/commit/?id=af91ae4946fec9e4d7ec1045376834e231630cea

(I had also tried to install FreeBSD 12.0 and OpenBSD 6.4 but both of
their installers failed to boot just after the kernel is loaded and
located. I am not sure if this is related to this or not.)

Best regards,
Masanori
