Comment 36 for bug 48556

Also worth noting is that the liveCD for Kubuntu 2006-06 (original release) doesn't seem to exhibit this problem. That is, I can boot up and use that version just fine.

I tried decompiling my DSDT last night. 8 warnings, no errors. I tried fixing the warnings and booting up with a replacement DSDT but got the same problem. I may well have not fixed the warnings or deployed my DSDT file properly. Additionally, seven of the warnings were concerning ignored return values on mutex acquires. It wasn't clear to me how to fix that so I just told it to wait indefinitely.
