Andrew, The attached file describes PCI bus EEH "Extended Error Handling" concepts and operation; could you drop this into the kernel documentation tree, at linux-2.6/Documentation/powerpc/eeh-pci-error-recovery.txt ? Signed-off-by: Linas Vepstas --linas p.s. It was not clear to me if the EEH patch previously sent (6 January 2005, same subject line) will be wending its way into the main Torvalds kernel tree, or not. I hadn't really gotten confirmation one way or another.
