Description James 2011-02-28 19:54:10 UTC 
User-Agent:       Mozilla/5.0 (X11; NG; Linux x86_64; en-GB; rv:1.9.2.13) Gecko/20110103 DW/3.6.13-1.Darwin Firefox/3.6.13

My wlan1 device does not show up after upgrading to 2.6.35.11-83.fc14.x86_64. The same machine works fine with 2.6.35.10-74.fc14.x86_64.

The machine is a Lenovo IdeaPad Y550P. Device:
06:00.0 Ethernet controller: Atheros Communications Inc. AR5001 Wireless Network Adapter (rev 01)

I attempted to modprobe ath5k on 2.6.35.11-83.fc14.x86_64 which returned without error, however the device did not show up. I saw no relevant output in dmesg. 



Reproducible: Always

Steps to Reproduce:
Boot into 2.6.35.11-83.fc14.x86_64
Actual Results:  
No wlan1.

Expected Results:  
wlan1 device should exist.

That doesn't really tell us what the adapter is. Run lspci with the -vnn option and post the output for just that device.

Also post the complete contents of /var/log/dmesg after booting each of the working and broken kernels (as separate plaintext attachments.)

Working kernel:

Comment 3 Stanislaw Gruszka 2011-03-16 14:34:32 UTC 
We have no ath5k specific changes between 35.10 and .35.11, so problem must be in 802.11 stack or pci subsystem,or perhaps somewhere else.

Can we get full dmesg output from working and not working kernel?
Comment 4 Stanislaw Gruszka 2011-03-21 07:57:42 UTC 
Is possible to get dmesg's?
