I recently upgraded my desktop mac to Precise and now can't get past the Ubuntu 12.04 splash page. The splash freezes with

[   19.931097] b32-phy0 ERROR: Firmware file "b43/ucode16_mimo.fw" not found
[   19.9311126] b32-phy0 ERROR: You must go to http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware and download the correct firmware for this driver version.  Please carefully read all instructions on this website.

written on it

This is when I choose 3.2.0-generic from the grub menu. If I choose to load up older kernels, I still get the same thing.

How can I make my computer finish booting again?

I'm able to ssh into the machine and poke around, but the actual screen freezes at the splash.

Will final version of 12.04 use the power management changes found in kernel 3.3

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are… >>> More
