    Having reviewed the patch and the trace I believe you need to take this
    up with vmware. All the patch does is slightly alter where the locking is
    done. I suspect vmware are blindly calling into the rtc_fops ioctl method
    directly in which case they just got burned.

    One way to check this would be to add a .ioctl method back which was

    printk("VMWare caught with pants down\n");

    if it prints that instead of or while crashing you know who is guilty.
