preemption imbalance?

I'm in the process of cleaning up a USB gadget driver for the MSP71XX platform and on boot I receive the following message: "initcall at 0x803f0ab8: msp71xx_udc_init+0x0/0x38(): returned with preemption imbalance" later followed by many: "BUG: scheduling while atomic: swapper/0x0000000a/0 Call Trace: [<8010775c>] dump_stack+0x8/0x34 [<8035aa90>] schedule+0xa2c/0xb14 [<801038f4>] cpu_idle+0x34/0x68 [<803d79cc>] start_kernel+0x394/0x538" although the kernel goes on initializing, init starts and I can login. Since msp71xx_udc_init() calls: platform_driver_register(&msp71xx_udc_driver) and that structure has entry points for the probe and remove functions. I'm assuming the probing/registering function is not releasing a lock or some other kernel resource properly. Would anyone on this list gadget driver experience have an idea which one it could be?
