Hi all, i read in "Understandig Linux Kernel" that Interrupt or exception handling can interrupt a process running in Kernel Mode" but if u insert a simple module having only while(1) loop, everything hangs. After that kernel is not able to handle the interrupts generated by keyboard or mouse. so can anybody tell me what is actually happening. Thanks and Regards, Deepak Joshi. ___________________________________________________________ NEW Yahoo!
