Hi, I have here some typical windowscentric Dell laptop with a b43 chipset that refuses to work due to something with DMA. lspci: 08:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) 08:00.0 0280: 14e4:4315 (rev 01) I installed the firmware using one of opensuse's scripts (install_bcm43xx_firmware, though it handles b43 and b43legacy according to the script's inner comments), which retrieves wl_apsta_mimo.o from mirror2.openwrt.org/sources/broadcom-wl-4.150.10.5.tar.bz2 and runs fwcutter on it. In dmesg, I then find on modprobe b43 verbose=3: b43 ssb0:0: firmware: requesting b43/ucode15.fw b43 ssb0:0: firmware: requesting b43/lp0initvals15.fw b43 ssb0:0: firmware: requesting b43/lp0bsinitvals15.fw b43-phy0: Loading firmware version 410.2160 (2007-05-26 15:32:10) b43-phy0 debug: b2062: Using crystal tab entry 19200 kHz. b43-phy0 debug: Chip initialized b43-phy0 debug: 64-bit DMA initialized b43-phy0 debug: QoS enabled b43-phy0 debug: Wireless interface started b43-phy0 debug: Adding Interface type 2 b43-phy0 ERROR: Fatal DMA error: 0x400, 0x0, 0x0, 0x0, 0x0, 0x0 b43-phy0 ERROR: This device does not support DMA on your system. Please use PIO instead. b43-phy0 ERROR: CONFIG_B43_FORCE_PIO must be set in your kernel configuration. ADDRCONF(NETDEV_UP): wlan0: link is not ready So, can I get PIO mode for free without recompiling? (Since CONFIG_B43_PIO=y already.) What other info needs to be provided to help resolve this? System is a 2.6.33.2-x86_64. thanks, Jan -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
