Hi, Can somebody reproduce this bug? http://bugs.centos.org/view.php?id=4220 dd if=/dev/zero of=/dev/my_usb_stick_device_name bs=4096 count=10000 can not be stopped with ctrl-c and is not responding to signals (count=10000 can be modified to give you enough time to test) The bug has been closed with the following comment: "As said: dd is in an uninteruptable state when you do that. This is not a bug" This is wrong, because IMHO dd should receive the signal after it finishes the current read()/write() and returns to user space, but this is not happening. How can I reopen the bug? Thanks Adrian Buciuman
