It does not appear to change the behavior of my machine in the slightest. And on my ASUS board(2.6.12-rc6 w/git8 and ur patch), I get the following: PCI: Cannot allocate resource region 0 of device 0000:02:00.0 PCI: Cannot allocate resource region 3 of device 0000:04:00.0 PCI: Failed to allocate mem resource #3:1000000@fe000000 for PCI: Bridge: 0000:00:0e.0 Where 02:00.0 is the USB controller, 04:00.0 is the sound card and 00:0e.0 is the bridge for the Broadcom ethernet adapter. I posted the entire lspci, dmesg and a barf from the tg3 module in the following post: http://lkml.org/lkml/2005/6/10/211 I have contacted ASUS for more assistance, but like their web site, it is intermittent at best. What can be done at this point? Sean
