No crash up to now, but the very same "hang" for a few seconds on "ifconfig wlan0 down". Interestingly this does only happen after a normal boot - once I did a suspend and resume (S3), there is no hang anymore. >> >> Hardware: Thinkpad T61p with Intel 4965 agn >> Software: Debian Lenny x86_64 with vanilla 2.6.27 kernel >> > Driver in 2.6.27 is not stable, please try to reproduce this in > current wireless-testing.git. I do not have the time to compile and test wireless-testing ATM, sorry. In fact I am annoyed by the fact that iwlagn is "known to be unstable" in a stable kernel release and that this even seems to be a totally normal thing... Once compat-wireless is working again on my system I will try that and check whether the hang still occurs. Current compat-wireless does not for me - compilation says make[1]: Entering directory `/usr/src/linux-2.6.27' /home/richard/Desktop/compat-wireless-2008-10-17/config.mk:44: "WARNING: You are running a kernel >= 2.6.23, you should enable in it CONFIG_NETDEVICES_MULTIQUEUE for 802.11[ne] support" and I did not find CONFIG_NETDEVICES_MULTIQUEUE using menuconfig. Loading the modules fails with tons of unknown symbols and disagreed versions (already at cfg80211 and mac80211 modules). Perhaps I should go back to Debian stock 2.6.26 kernel - but there Ad-Hoc is broken on iwl4965, although it was working without problems earlier in 2.6.24.
