thinkpad t21, linux 2.4.28-gentoo-r5, and ACPI

If you find yourself running this kernel, make sure you remove all ACPI support from the kernel if you want to use the onboard 3Com Tornado 3c556B CardBus ethernet adaptor. You used to be able to get away with the acpi=off kernel parameter with 2.4.26-gentoo-rn kernels, but this doesn’t work any more.

This has been a Nerd Public Service Announcement.

  1. I have the same problem with the newest 2.6 kernels – what good is turning off acpi if I want this functionality? I’m considering pilfering a different mini-pci adapter from somewhere…
