[Bug 554265] Re: thinkpad_acpi: WARNING: Outdated ThinkPad BIOS/EC firmware

[Vladimir Pycha]

Majestyx: Although your BIOS is already up-to-date, you need to update
the Embedded Controller (EC) firmware (ECP) too as stated in
http://www.thinkwiki.org/wiki/BIOS_Upgrade. The latest EC firmware
version for your T40p laptop is EC 1RHT71WW-3.04. You have now EC
1RHT66WW-3.00a according to BootDmesg.txt attachment.

I have successfully followed the instructions on
http://www.thinkwiki.org/wiki/BIOS_Upgrade to update the BIOS and ECP on
my T41, just like Bruno Girin. My ECP was already up-to-date so I
updated only the BIOS. It solved the problem for me as expected.

The primary cause of the problem is outdated BIOS or ECP or both.
The secondary cause are these 2 consecutive lines in the output of dmesg, as they have the WARNING level:
[   73.321116] thinkpad_acpi: WARNING: Outdated ThinkPad BIOS/EC firmware
[   73.321119] thinkpad_acpi: WARNING: This firmware may be missing critical bug fixes and/or important features
The third cause is Kernel Oops thing not liking WARNING lines in the output of dmesg.

After BIOS upgrade the Kernel Oops thing showed me still one more time.
It showed with the second line. Sooner it always showed with the first
line. But on the output of dmesg was no WARNING line so it was somehow
cached from the previous session. On the next reboot it was OK.
