Comment (by [EMAIL PROTECTED]):
Retested with r1644 and activated kernel symbols. Still the same picture
:(
{{{
wlan: 0.8.4.2 (svn r1644)
ath_hal: module license 'Proprietary' taints kernel.
ath_hal: 0.9.17.2 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413,
REGOPS_FUNC)
ath_rate_sample: 1.2 (svn r1644)
ath_pci: 0.9.4.5 (svn r1644)
}}}
The problem can be reproduced by destroying the autocreated master device
(which is default on !OpenWrt) and twice creating a managed device
afterwards:
