Thread: Ubuntu 11.04 freezes on T41

hi folks,

since did this, gnome desktop freezes after connected wireless lan.

syslog gave me hint mistake in loading module intel wireless card...

syslog:

code:

jun 21 14:40:16 blackbox pulseaudio[1508]: module-alsa-card.c: failed find working profile. jun 21 14:40:16 blackbox pulseaudio[1508]: module.c: failed load  module "module-alsa-card" (argument: "device_id="29" name="platform-thinkpad_acpi" card_name="alsa_card.platform-thinkpad_acpi" tsched=yes ignore_db=no card_properties="module-udev-detect.discovered=1""): initialization failed. jun 21 14:40:19 blackbox networkmanager[479]: <info> wifi disabled radio killswitch jun 21 14:40:19 blackbox networkmanager[479]: <info> (eth1): device state change: 3 -> 2 (reason 0) jun 21 14:40:19 blackbox networkmanager[479]: <info> (eth1): deactivating device (reason: 0).

any or hints appreciated thx @ lot!!!

syslog gave me hint mistake in loading module intel wireless card...

code:

jun 21 14:40:19 blackbox networkmanager[479]: <info> wifi disabled radio killswitch  jun 21 14:40:19 blackbox networkmanager[479]: <info> (eth1): device state change: 3 -> 2 (reason 0)  jun 21 14:40:19 blackbox networkmanager[479]: <info> (eth1): deactivating device (reason: 0).

in not expert opinion, own t40 , t60 , have owned 2 t23s, tells nothing useful. says wireless switch, in case, fn+f5, believe, turned wireless off , network manager deactivated device.

i'd see, after freezes , reboot:

code:

sudo cat /var/log/syslog | grep -e eth1 -e <wireless_driver> -e error

if output sparse, check syslog.1.

find out wireless driver with:

code:

sudo lshw -c network

here mine:

*-network
description: wireless interface
product: pro/wireless 3945abg [golan] network connection
vendor: intel corporation
--- snip ---
configuration: broadcast=yes driver=iwl3945 driverversion=2.6.38-8-generic firmware=15.32.2.9 ip=192.168.1.101 latency=0 link=yes multicast=yes wireless=ieee 802.11abg
resources: irq:48 memory:edf00000-edf00fff

therefor, in case, i'd substitute iwl3945 above.
