If "reboot" is carried out than there is no problem and the wifi works properly (even if done from Gnome - Gnome seems to have no relation to the problem). So what could lead to "ath0: time out" after shutting down or halting the system? I noticed that there are irq storms on irq 17 which is the wifi irq (interrupt storm detected on "irq17:"; throttling interrupt source). Something else that I am not sure to have relevance - after shutdown during the start-up ath0 is reported to use autoselect mode 11g: (below is from dmesg) ath0: flags=8843 metric 0 mtu 2290 ether 00:19:7e:91:xx:xx nd6 options=29 media: IEEE 802.11 Wireless Ethernet autoselect mode 11g status: associated After the boot has finished the mode changes to 11a: #ifconfig ath0 ath0: flags=8843 metric 0 mtu 2290 ether 00:19:7e:91:xx:xx nd6 options=29 media: IEEE 802.11 Wireless Ethernet autoselect mode 11a status: associated Do you have any idea where to look for now? Regards, Lyubomir P.S. I will try to play with acpi_ibm.ko and see if things change if I make it auto-load.
