First of all, do the command objdump -d -l drivers/ide/ide-core.o > ide_core.dump Next, open ide_core.dump with less or your favorite editor and search for the start of init_irq. Note that address. Add your offset of 0x18D to that value and find the instruction at that address. Move up in the file until you find a line that looks like /home/finger/linux-2.6/drivers/ide/ide-probe.c:1054 That will be the source line that oopsed. Post that information. Thanks, Larry Once this is open, search
