font-family:Arial'>I’m really hoping Mark Greer or Dale Farnsworth sees
this email. In my current project, we are in the process of updating a board
that has a Marvell mv64462 system controller and a Freescale mpc7447A processor
on it. The board was originally developed with Gentoo Linux 2.6.9, but we have
ported Linux 2.6.24 kernel onto it. The new kernel is working well thanks to
help from people on this list. However, in examining the differences between
the 2 kernels, I can see that the 2.6.24 kernel registers no interrupt error
handling routines (see PCI Error Report Register Map in the Marvell
documentation). The error handlers for cpu, sram, and specifically for the PCI
bus that were previously in:<o:p></o:p></span></font></p>

font-family:Arial'>Can someone who is familiar with the history of the
ppc->powerpc migration for this architecture help me figure out why the
error handling wasn’t ported over? Is there some reason for this, such as
it didn’t work properly or had some disadvantages? Is this error handling
done in 2.6.24 in some more generic manner that I have not yet found? Is this
an exercise left for me to implement?<o:p></o:p></span></font></p>
