Subject: pci: is reset incomplete?
Date: Mon, 14 Sep 2009 18:48:22 +0300	[thread overview]
Message-ID: <20090914154822.GA3745@redhat.com> (raw)

Hi!
pci bus reset does not seem to clear pci config registers, such as BAR
registers, or memory space enable, of the attached devices: it only
clears the interrupt state.

This seems wrong, but easy to fix.

Comments?
