Does it oops? Does it call panic()? If so, how do you know this, if your only means of debugging it was pm_trace? I mean, it could be that the machine was hanging during uhci resume rather than oopsing or panicing? Anyway, it might be worth setting up netconsole (Documentation/networking/netconsole.txt) to see if you can get more information out of the machine. Sometimes netconsole doesn't work very well across suspend/resume, because the net device itself gets suspended too. But often it emits useful info.
