Just to make sure to avoid all confusion. The title of this thread should
be
"[PATCH] Fix ide-disk.c oops caused by hwif->pci_dev == NULL"
And this is the patch that was acknowledged by Andrew and that fixes the
issue AFAIK. This patch needs to be included in 2.6.13. Lets make sure
that we are all on the same page on this patch now:
---
From: Christoph Lameter <[email protected]>
There is one additional place where pcibus_to_node is used with the hwif
that we did not cover.
- Move hwif_to_node to ide.h
- Use hwif_to_node in ide-disk.c
