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 The primary cause of the problem is outdated BIOS or ECP or both.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these 2 consecutive lines in the output of dmesg, as they have the WARNING level: [ 73.321116] thinkpad_acpi: WARNING: Outdated ThinkPad BIOS/EC firmware [ 73.321119] thinkpad_acpi: WARNING: This firmware may be missing critical bug fixes and/or important features The third cause is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. -- thinkpad_acpi: WARNING: Outdated ThinkPad BIOS/EC firmware https://bugs.launchpad.net/bugs/554265 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
