64-bit Linux OS's + ASUS P8Z68-V PRO/GEN3 = :(

Since I'm not on the command line much anymore at work I decided to add another small SSD to my main box @ home and dual boot Win7 + Linux - hadn't fully committed to any one distro yet.

I've run into a bit of a problem. In fact, my exact problem is described in this thread on the Ubuntu forums: http://ubuntuforums.org/showthread.php?t=2114055

Summary: when I boot into a 64-bit Linux environment, I lose all USB functionality in my machine. I've tried Fuduntu, Linux Mint 14, Fedora 18, and Ubuntu 12.10 all with the same result.

I have an Asus P8Z68-V Pro/Gen 3 with the latest BIOS update. http://www.newegg.com/Product/Produc...82E16813131790.

The rub, however, is that the fix in the Ubuntu thread above doesn't apply to me since this particular board I have doesn't have an IOMMU implementation. Thus I can't enable it in the BIOS.

I scoured my BIOS for anything I thought may get me up and going but alas no love.

Am I screwed?
 
It sounds like a tough hardware/BIOS issue, you might have better luck with virtualized linux on that particular machine. Personally I find it more useful to use VMs than to dual boot. I would hit up the ASUS tech support folks for clues.
edit: link
It looks like the OP and several others in the link above also cannot enable IOMMU, with one guy saying it has worked fine for a long time. You might consider looking at older versions of the BIOS where the menu options are all present or the settings are on by default.

I agree with all of this, especially contacting Asus. Asus may or may not help, but by asking it tells them people want GNU/Linux support. Dual booting is a PITA, and I avoid it if at all possible. VMs are the way to go if your use case supports it.

Edit:
32bit isn't terrible on GNU/Linux. It handles memory better than Windows32. Something to consider.

I've had sound issues in the past with Ubuntu that were not a problem with any other distro, so I would recommend trying a non-Ubuntu distro like Linux Mint Debian. Ubuntu just has a way of fscking stuff up from time to time.

A distro with a newer kernel may also help.

That may actually be the problem, though. Ubuntu and Fedora are using bleeding-edge kernel and packages, where Debian is using stable, older kernels. The issues I had in the past were Ubuntu-specific, where Mandriva and Fedora with the same kernel gave me no problem.
 
Thanks for the responses guys. I've been super busy with work and sort of lost my steam with tinkering on this project. I may try some different distros with older/newer kernels in the near future.

Out of curiosity, is anyone here using a UEFI FW-based motherboard w/a 64-bit flavor of Linux? As opposed to ye olde BIOS FW mobos.
