fc5t3 suspend option soft lockup

I have a desktop PC and am trying fc5t3. It's fully yum updated. For fun, I tried System->Shutdown->Suspend. I get a text screen and : Stopping tasks :===<3> BUG: soft lockup detected on CPU#0! Pid: 643, comm cx88 tvaudio (then a register dump i guess...) I have to reset the PC to get it back up. I guess this is a feature for laptops or something? Anyway, thought I'd mention it. The box is a mini PC, IDEQ Biostar 210V. # rpm -qa | grep kernel kernel-2.6.15-1.1977_FC5 -- SW
