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: http://people.freebsd.org/~scottl/pci_command_fixes.patch Thanks, Scott
