I've been using cgminer v3.3.0 with my ATI/Radeon 5700 successfully since 3.3.0 was released.  Recently, the cpu was pegged at 100% and the system very sluggish as a result.  I rebooted and now I can't get cgminer to startup.  If I disable-gpu, it will start, otherwise it hangs with the following messages:

    cgminer --verbose -D -T -c cgminer.conf.empty
    [2013-08-22 13:33:00] Started cgminer 3.3.0                   
    [2013-08-22 13:33:00] Loaded configuration file cgminer.conf.empty                   
    [2013-08-22 13:33:00] RES: thread starting


Additionally "./cgminer --ndevs" will hang.

The system runs linux (bamt) and the GUI looks o.k., but I'm afraid that my GPU is dying.

What else can I try?

--E
