2.6.33.rc1-git3 - regression in rt61pci driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I'm not subscribed, so please cc me on any reply.

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

          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

6. /proc/net/dev contains:

Inter- |   Receive
                               |  Transmit

  0       0    0    0    0     0       0          0

7. dmesg shows the following messages triggered by insertion of the card:

I'll see if I can find time for a bisect session tomorrow, but let me
know if I can supply any additional diagnostics.

Thanks
