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?
