Subject: Wireless problem in 3.4-rc5
Date: Tue, 01 May 2012 14:58:20 -0500	[thread overview]
Message-ID: <4FA0405C.8050101@lwfinger.net> (raw)

Hi,

After upgrading to 3.4-rc5 from wireless-testing, one of my boxes fails to scan 
and gets a "Network down" message for all wireless devices. The code in 3.4-rc4 
was OK, thus I bisected to find the offending commit. The one that broke my 
wireless is commit 3a25a8c entitled "mac80211: add improved HW queue control".

On my main laptop, this patch causes no problems. On a 3rd box, a BCM4312 (b43) 
is OK, but an RTL8187L (rtl8187) also fails in the same manner.

The problem is not in the configuration as I copied the one from the box that 
works to the one that fails, and it still fails. The only difference is that the 
working system has 2 CPUs and the ones that fail are uni-processor; however, if 
I boot with maxcpus=1, my main machine still works.

Any suggestions of things to try will be appreciated.

Larry
