I've built and installed today's -git kernel (v2.6.33-rc1-225-gc9f937e) and find that my (rt61pci) wireless card no longer works. All the usual drivers are loaded when I insert the card. The card works fine with 2.6.32.2 (as long as I disable power saving). The symptoms are that: 1. The file /proc/net/wireless never appears 2. iwconfig gives "wlan0 no wireless extensions." 3. ifconfig wlan0 up succeeds 4. iwconfig wlan0 essid MYSSID gives Cannot read /proc/net/wireless Error for wireless request "Set ESSID" (8B1A) : SET failed on device wlan0 ; Invalid argument. 5. ifconfig -a gives: wlan0 Link encap:Ethernet HWaddr 00:11:50:DE:04:F4 BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) 6. /proc/net/dev contains: Inter- | Receive | Transmit face |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressed lo: 600 12 0 0 0 0 0 0 600 12 0 0 0 0 0 0 wlan0: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 7. dmesg shows the following messages triggered by insertion of the card: pcmcia_socket pcmcia_socket0: pccard: CardBus card inserted into slot 0 pci 0000:03:00.0: reg 10: [mem 0xffff8000-0xffffffff] pci 0000:03:00.0: BAR 0: assigned [mem 0xf4000000-0xf4007fff] pci 0000:03:00.0: BAR 0: set to [mem 0xf4000000-0xf4007fff] (PCI address [0xf4000000-0xf4007fff] cfg80211: Calling CRDA to update world regulatory domain cfg80211: World regulatory domain updated: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp) (2402000 KHz - 2472000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) (2457000 KHz - 2482000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) (2474000 KHz - 2494000 KHz @ 20000 KHz), (300 mBi, 2000 mBm) (5170000 KHz - 5250000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) (5735000 KHz - 5835000 KHz @ 40000 KHz), (300 mBi, 2000 mBm) rt61pci 0000:03:00.0: enabling device (0000 -> 0002) rt61pci 0000:03:00.0: PCI INT A -> Link[LNKD] -> GSI 11 (level, low) -> IRQ 11 rt61pci 0000:03:00.0: setting latency timer to 64 phy0: Selected rate control algorithm 'minstrel' Registered led device: rt61pci-phy0::radio Registered led device: rt61pci-phy0::assoc I'll see if I can find time for a bisect session tomorrow, but let me know if I can supply any additional diagnostics.
