Hi Ralph, perhaps you could not attach your .vcf files anymore? If your driver implements non-blocking read() and write() functions, then you don't have to sleep. Else others have commented on the alternative to sleep_on().
For non-blocking: Just use poll_wait() in your poll() function and wakeup_interruptible when there data available on your Qs. Then user program's select() and poll() system calls will work properly.
