booting and mounting PCIIDE: kernel access of bad area

[KokHow Teh]

Hi;
      I have rebuilt arabella linux kernel with PCI IDE support. However,
the kernel bootup crashes with "kernel access of bad area" message. I think
it has something to do with the IDE base addess setup. I have tried to
change the ide0=base,ctl but to no avail. Hope you are able to advise me on
that. Thanks.

Regards,
TEH
