wifi dies if i switch console while downloading
If I start a download using curl (in a tty) or firefox, then switch consoles using ctrl-alt-X or alt-X, the following messages show up in syslog and the wireless connection fails.
I can switch consoles with no problems while browsing or with irc open, but when downloading it causes this problem.
Mar 1 17:48:58 <host> dhcpcd: wlan0: carrier lost
Mar 1 17:48:58 <host> kernel: No probe response from AP 00:11:22:22:11:11 after 500ms, disconnecting.
Mar 1 17:48:58 <host> kernel: cfg80211: Calling CRDA to update world regulatory domain
Also, I use radeondrmfb. Because this is a 64-bit powerpc machine (out of the norm hardware), I think it is possible that a "hiccup" is occurring at the kernel level when radeondrmfb is handling the console switch, and that is causing/preventing whatever manages the wireless card to fail to process any AP probe responses, leading to the kernel seeing no response and disassociating. could this be possible? I have rebuilt a kernel with verbose printk of the syslog "no probe response" message shown above, and am going to test it tomorrow.
thanks for your help
