Correa" Cc: wireless Content-Type: text/plain; charset=ISO-8859-1 To: unlisted-recipients:; (no To-header on input) Sender: linux-wireless-owner@vger.kernel.org List-ID: OK, I found new data on my problem, this might shed light on some fix/enhancement for the driver. When the system starts, the iomem of the 4311 card is specified to be pci 0000:06:00.0: reg 10 32bit mmio: [0xd0000000-0xd0003fff] The iomem of 4311 cannot be allocated: arch/x86/pci/i386.c:173: pci 0000:06:00.0: BAR 0: can't allocate resource the next two instructions of file i386.c mean that the iomem range converts from 0xd0000000-0xd0003fff to 0x000000-0x003fff. Then b43-pci-bridge tries to allocate this iomem resource, which is invalid: drivers/pci/setup-res.c:290: b43-pci-bridge 0000:06:00.0: device not available because of BAR 0 [0x000000-0x003fff] collisions drivers/base/dd.c:143: b43-pci-bridge: probe of 0000:06:00.0 failed with error -22 The 4311 card (06:00.0) is in the PCI Express port 00:1c.2, with resources that are reported later: pci 0000:00:1c.2: PCI bridge, secondary bus 0000:06 pci 0000:00:1c.2: MEM window: 0x88000000-0x880fffff After booting, lspci -vvv shows: 00:1c.2 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 3 (rev 01) (prog-if 00 [Normal decode]) Memory behind bridge: 88000000-880fffff 06:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01) Region 0: Memory at 88000000 (32-bit, non-prefetchable) [size=16K] 16K = 3fff. Well then; the b43 controller stops probing my 4311 card because the wrong resource is probed for. I am not sure who should I direct this message to. -- Fabio Andr?s Correa Dur?n
