You need to use System.map to figure out what routine this crashed in. You need a backtrace/stack dump Then you need to create assembly for the file in question: gcc -Wa,ah, -Wa,al and figure out what the assembly was doing when it crashed. And then read the source code to see why. KDB makes this a *lot* easier. --linas ** Sent via the linuxppc-dev mail list.

When you get an "access of bad area" oops have a look at the DEAR register (I think you misspelled it as DAR above). 0x3f9 is the base address of COM1 on an x86 machine (http://www.sput.nl/hardware/io.html). My guess is you've got something wrong with your UART code. I believe this is where your (current) problem lies. Just a guess. Trevor ** Sent via the linuxppc-dev mail list.
