After much messing around I have found the point on current where it hangs. It seems to hang during the PnP probe: isa_probe_children: probing PnP devices Is there anyway I can stop this probing of PnP devices? I have tried adding "optons PNPBIOS" to the kernel but it causes the kernel to panic. If I drop into the debugger and type panic, the kernel seems to be stuck in mp_lock. I also cant seem to get the kernel to save core. The bios doesnt have an option to disable PnP. Any ideas on what else I can do?
