i really dont know what this signal is for. But with the help of the NIP I think u can see which function iin your application is causing this oops. Hoping tha you can enter the atleast ur bash (OR did u say that ur application is getting run just after boot before bash) you can exeute this command on the object file of the kernel (vmlinux) use objdump -dS --start-address=NIP(or u can have some instructions before that) --stop-address= (anything after NIP ) (but be sure to narrow the range).... this will tell u which function is causing this problem. If u have another image u can boot with that image and execute this.... -raghu. On Wed, 6 Nov 2002, Usman S. Ansari wrote: > Hello, > > Kernel is sending signal 8 to itself.
