Subject: WARNING: at net/wireless/chan.c:19 rdev_fixed_channel
Date: Sat, 08 Aug 2009 23:18:49 +0300 [thread overview]
Message-ID: <87my6akqja.fsf@litku.valot.fi> (raw)
I resumed my thinkpad x60s laptop (iwl3945, 32bit, old wpa_supplicant,
latest wireless-testing plus Johannes' siwfreq locking fix) and got the
warning below. Everything still worked, it automatically associated to a
WPA2 network and I'm sending this over that connection.
I have seen the page table error since rc2 or so, and I have been too
lazy to investigate it. I assume it's not related to the warning.
