Well I'm at it again, and it still hangs and I found why. I have dprinted jiffies and it never advances during the loop at do_xor_speed. There for it is stuck in an endless loop. I have also dprinted current_kernel_time() and it returns the same constant value as well. Note that it does usually work on UML, only during the modprobe of xor.ko while that test is running. It looks like some lucking is preventing the clock from ticking. However ktime_get_ts does work for me so I changed the code as below, so I can work. See how I put several safety guards, to never get hangs again. And I think my time based approach is more accurate then previous system. UML guys please investigate the jiffies issue? what is xor.ko not doing right?
