Can you derive a simple demo code from your application so that we can give it a try as well? I have an emulator here (qemu) where I can easily step into such issues (when they trigger on my box too...). If you want to dig deeper on your own: there is a kgdb add-on patch available for 2.6.16 (not 2.6.17 as falsely claimed by the readme) . Jan  http://download.gna.org/adeos/patches/v2.6/i386/kgdb/
