Subject: [PATCH] handle Toshiba deskstation PCI-PCI bridge
Date: Mon, 22 Mar 2004 13:06:48 -0600 [thread overview]
Message-ID: <405F3948.7040901@netscape.net> (raw)

I have a Toshiba Tecra 750 CDM laptop mounted in a Toshiba docking
station which has PCI slots. In all recent kernels the PCI-PCI bridge
is not handled correctly and the PCI cards in the docking station are
inaccessable because of PCI conflicts. The enclosed patch against
kernel 2.6.4 fixes this in a manner similar to the fix for a PCMCIA
issue in this device discussed here about a year ago.
These are the messages I get without this patch:
