Davem,
This patch is generically needed for recovery from PCI errors,
and not just the tg3 that Matt is working on.
Matt, there are also several msi-related bugs in the pseries
architecture implementation, those patches will go out to
Paul Mackerras seperately. I was hoping today ... but things
came up. One little iddy-biddy problem is that the pseries
is not actually *saving* the msi state, and so, ahem, the
restore isn't quite working out either. I'm still trying
to navigate around that.
