I've tried the master branch of bcm43xx-wireless-dev.git for the first time. The results are not encouraging so far (although I'm quite new to this chipset). drivers/ssb/driver_mips/mips.c includes asm/time.h, which is missing on x86_64. It also refers to struct ssb_serial_ports, which is not defined anywhere. drivers/ssb/driver_pci/pcicore.c refers to SSB_PCICORE_SBTOPCI1_CFG1 that is not defined anywhere in the kernel. I could send you huge logs, but I think it's already a clear sign that you didn't compile-test the current tree with CONFIG_SSB_DRIVER_MIPS enabled. Things are better if it is disabled. In case you haven't seen those warnings: /home/proski/src/linux-2.6/drivers/net/wireless/d80211/bcm43xx/bcm43xx_main.c:843: warning: 'bcm43xx_wireless_core_mark_inactive' defined but not used /home/proski/src/linux-2.6/drivers/net/wireless/d80211/bcm43xx/bcm43xx_main.c:3032: warning: 'bcm43xx_bluetooth_coext_enable' defined but not used I could compile the code, and it even loaded as a module, but the kernel oopsed once I brought wlan0 up by ifconfig. bcm43xx_d80211: Adding Interface type 2 bcm43xx_d80211: Found PHY: Version 4, Type 2, Revision 8 bcm43xx_d80211: Found Radio: Manuf 0x17F, Version 0x2050, Revision 2 bcm43xx_d80211: Loading firmware version 351.126 (2006-07-29 05:54:02) bcm43xx_d80211: Radio turned on bcm43xx_d80211: FIXME: Possibly broken code in bcm43xx_phy_initg() at /home/proski/src/linux-2.6/drivers/net/wireless/d80211/bcm43xx/bcm43xx_phy.c:1650 bcm43xx_d80211: Chip initialized Unable to handle kernel NULL pointer dereference at 0000000000000000 RIP: [] dma_alloc_coherent+0x52/0x23f PGD 50d1067 PUD 5201067 PMD 0 Oops: 0000 [1] SMP CPU 1 Modules linked in: bcm43xx_d80211 ssb Pid: 2623, comm: ifconfig Not tainted 2.6.20-rc3 #5 RIP: 0010:[] [] dma_alloc_coherent+0x52/0x23f RSP: 0018:ffff810005127bd8 EFLAGS: 00010206 RAX: 0000000000000000 RBX: 0000000000003500 RCX: 00000000000010d4 RDX: 00000000ffffffff RSI: 0000000000001000 RDI: ffff81000196c3a8 RBP: 00000000000010d0 R08: ffff81001f6d1600 R09: 0000000000000004 R10: 0000000000000001 R11: ffff810001122c60 R12: 0000000000001000 R13: ffff810001b96000 R14: ffff81000196c3a8 R15: 00000000ffffffff FS: 00002b411b2133b0(0000) GS:ffff810001827440(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 0000000000000000 CR3: 0000000015fdf000 CR4: 00000000000006e0 Process ifconfig (pid: 2623, threadinfo ffff810005126000, task ffff81001f58d180) Stack: ffff81001ee6a3c0 ffff81001ee6a3e8 ffff810001b96000 0000000000003500 ffff81001ee6a3c0 0000000000000080 ffff810001b96000 0000000000000000 0000000000000000 ffffffff88019966 0000000000000005 0000000100000036 Call Trace: [] :bcm43xx_d80211:bcm43xx_setup_dmaring+0x1a7/0x460 [] :bcm43xx_d80211:bcm43xx_dma_init+0xc0/0x290 [] :bcm43xx_d80211:bcm43xx_wireless_core_init+0x78f/0x9f1 [] mntput_no_expire+0x19/0x77 [] do_page_fault+0x40b/0x74a [] :bcm43xx_d80211:bcm43xx_add_interface+0x67/0xeb [] ieee80211_open+0x1c6/0x2c5 [] dev_open+0x2f/0x6e [] dev_change_flags+0x5a/0x119 [] devinet_ioctl+0x235/0x59c [] sock_ioctl+0x1c8/0x1e5 [] do_ioctl+0x21/0x6b [] vfs_ioctl+0x25c/0x275 [] sys_ioctl+0x3c/0x5c [] system_call+0x7e/0x83 Code: 4c 23 38 49 39 d7 0f 46 e9 49 8d 44 24 ff 83 ca ff 49 89 c5 RIP [] dma_alloc_coherent+0x52/0x23f RSP CR2: 0000000000000000 It's Fedora Core 6 x86_64 on a Dell Latitude with Core 2 Duo and an PCIe wireless card.
