Bug Description
Binary package hint: linux-image-
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@
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
