Re: nvidia 100.14.19 + ipw3945: system freezes
Nvidia uses hot keys to switch between displays, as compiz does to initiate different effects, if you have an extra monitor output on your laptop that may be an issue. The allocated resource regions messages may be your recovery partition, or if your laptop supports playing DVD's without starting the OS, it will have a partition for that, I get those messages too. I always thought the problem with my laptop was always with the irq, as it was always last to be allocated, and was only fixed by commenting out those parts of my dsdt, as for others on several different forums. I did not try the kernel options route, but checking for a custom dsdt is part of the recent kernels, if checked in your kernel configuration file. It is then a matter of supplying a dsdt.aml file in the correct directory and running mkinitramfs, unless gentoo is different in that regard. Good luck!
