Hello

I'm having a bit of grief with 2.6.8.1 on a Toshiba Tecra 9100.  Earlier 2.6
kernels worked fine including 2.6.7.  An afternoon of kernel-fiddling has
shown that CONFIG_EDD causes the following oops whilst booting.

I'm now running 2.6.8.1 with CONFIG_EDD disabled and it works a treat.

Problem is reproducable and I'm happy to test changes etc. as required.
