Latest working kernel version: Earliest failing kernel version: 2.6.24 Distribution: Ubuntu 8.04 x64 Hardware Environment: Acer 5220, 2G ram, Celeron M530 Software Environment: NetworkManager=0.6.6-0ubuntu5, wpa_supplicant=0.6.0+0.5.8-0ubuntu2 Problem Description: When using the old firmware the driver works fine, but when replacing it with the new firmware the connection works only shortly and errors appear in dmesg. [ 796.673070] b43-phy2: Loading firmware version 410.2160 (2007-05-26 15:32:10) [ 797.994369] b43-phy2 debug: Chip initialized [ 797.995115] b43-phy2 debug: 32-bit DMA initialized [ 798.004901] Registered led device: b43-phy2::tx [ 798.005476] Registered led device: b43-phy2::rx [ 798.005940] Registered led device: b43-phy2::radio [ 798.006460] b43-phy2 debug: Wireless interface started [ 798.029348] b43-phy2 debug: Adding Interface type 2 [ 798.042529] ADDRCONF(NETDEV_UP): wlan0: link is not ready -> [ 799.407607] b43-phy2 ERROR: PHY transmission error (...)

Webpages load for a little while, but then they completely stop loading. And as the support for the old firmware is supposed to be stopped soon, the new firmware should work at that point. Steps to reproduce: Associate to WPA encrypted access point with 2.6.25.6-vanilla. Please let me know what further information I can provide.
Created attachment 16540 [details] 2.6.26rc6 kern.log excerpt I tried unloading and reloading the module a couple times. Exchanged the firmware back and forth. Whenever the new firmware was used, the network connection was working only for a little while.
For more logs of my system please see another recent bug here: http://bugzilla.kernel.org/show_bug.cgi?id=10914
Actually the same problem appears with the old firmware, only much later. Around one to two hours of constant traffic and the connection breaks off with PHY errors. Any idea how we can debug this? I think it would be pretty tough for some people if the old firmware is cancelled but the new doesn't work yet. I would be glad for any help!

It seems like this bug is at least alleviated in 2.6.25.7.
The bug really is fixed in 2.6.25.7.
