Comment 38 for bug 566149

@Karl Ryder: FTR, I just yesterday followed the steps at https://wiki.ubuntu.com/KernelTeam/MainlineBuilds to install the kernel at http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2010-05-06-lucid/ . It fixed the USB suspend problem and it didn't cause many other problems. I think it might have broken HDMI audio, but I didn't use that anyway ("normal" audio through the internal speakers is fine). I haven't noticed anything else broken yet, although there well may be. But note that you can still boot to the older kernel after installing a new one too, so I'd reconsider trying it.
