"modprobe airo" hangs on ThinkPad T30

[Thomas Hood]

Binary package hint: linux-image-2.6.24-16-generic

When I installed hardy I found that it took three minutes to boot.
Most of the time the machine appeared to be doing nothing.
"ps" showed that there were many modprobe processes stuck in
the D state. The culprit turned out to be the "modprobe airo".

I worked around the problem by adding "blacklist airo" to a file in
/etc/modprobe.d/.

Tests reveal that this command never returns:

    root@timulak:~/src/pollin/svn-pollin# modprobe airo

In another terminal I see the following processes listed in the output of "ps -Alf":

    4 D root 15453 15436 0 80 0 - 450 - 15:08 pts/1 00:00:00 modprobe airo
    1 S root 15457 7 0 75 -5 - 0 - 15:08 ? 00:00:00 [khelper]
    4 D root 15458 15457 0 80 0 - 431 - 15:08 ? 00:00:00 /sbin/modprobe -q -- aes

See also #189398.

I will now reboot to try the workaround described there. :)

It worked. I commented out two lines in modules.alias

    modules.alias:#alias aes padlock_aes
    modules.alias:#alias aes geode_aes

Result:

root@timulak:~# modprobe airo
root@timulak:~# lsmod

I had the same problem on a T41.
This fix worked for me.
I commented out two lines in:
/lib/modules/2.6.24-16-generic/modules.alias

This is a real problem for thinkpad owners with airo wireless.
In addition to the delay at boot, the wireless does not work without this fix.

This is a dup of #205715

Hi Thomas,

I'm going to mark this as a duplicate of bug 189398. Please continue to follow up with any additional information to that report. Thanks.

The kernel proposed for intrepid doesn't have this problem.
