PCMCIA hang running kernel 2.6.8-1 or 2.6.9-rc1


I am running RedHat WS3.0 with new 2.6.8-1 and 2.6.9-rc1 kernel, when I enalbe my PCMCIA with my external device attach to my CardBus card, I will hang during boot up with following message:
Even I disable PCMCIA (chkconfig pcmcia off) and it will boot up into run level 5, then I manually insert the PCMCIA modules one by one (pcmcia_core, yenta_socket, ds), it will hang on loading ds.o modules with the same kernel_thread error code:
