Hi Robert,
Thanks for your reply. I'm not sure if the kernel config has changed as I
am using the stock ubuntu kernels. Perhaps I should log a bug with
ubuntu. If it helps, the pata_sil680 module is loaded (visible in
/proc/modules) when I boot either kernel, it just doesn't detect my 750GB
drive in the 2.6.24 based kernel.
