All,

Subversion rev 250418 affected approximately 63 drivers by making them =
vulnerable to resource allocation failures on motherboards with buggy =
BIOSes.  The revision itself is good, but it needs to address these =
drivers and bring them up to what is, in effect, a modified way for =
drivers to manage their PCI resources.  If you've been seeing something =
like the following message since June 24/27, then you need this patch:

mps0: <LSI SAS2116> port 0xd000-0xd0ff mem 0xfb79c000-0xfb79ffff irq 19 =
at device 0.0 on pci4
mps0: PCI memory window not available
device_attach: mps0 attach returned 6

The patch originated from John Baldwin, I merely fixed up a few nits and =
am passing it around for review and testing.  Please find it here:

Thanks,
Scott
