Description of problem:
Loading this kernel on my Thinkpad T41 with Cisco Airo 350 mini-pci,
boot hangs when enabling eth1. No error message appears, and it's too
early to get messages in the log. Three-finger salute initiates reboot.
The indicator light flashes rapidly.
Everything was working fine with kernel-2.6.6-1.435.2.3. The card
currently has firmware 5.00.03.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install kernel-2.6.7-1.494.2.2
2. Boot kernel-2.6.7-1.494.2.2 on a machine with a properly-configured
and working airo minipci card.
Actual Results: Hangs when starting eth1. Wireless indicator light
Expected Results: Starts eth1 successfully. Wireless indicator
I have a Thinkpad R40 and a Cisco Airo 350 mini-pci with Firmware
Version: 5b00.08 and using the same kernel the computer will boot
but is not able to use the card correctly. I got it working using
When trying to unload the module on 2.6.7 I get:
Aug 10 10:47:42 borg kernel: airo: Unregistering eth1
Aug 10 10:47:42 borg net.agent: remove event not handled
Aug 10 10:47:52 borg kernel: unregister_netdevice: waiting for eth1
to become free. Usage count = 7
My problem persists with kernel-2.6.8-1.521. Starting eth1 at boot
results in a hang with the indicator light flashing rapidly. Starting
by hand after boot completes works fine. kernel-2.6.6-1.435.2.3 works
This problem appears to be related to Bug #112824 and some others
regarding hardware initialization and hotplugging. Following the
suggestion there, I upgraded initscripts to initscripts-7.77-1 from
the development tree (and mkinitrd to the devel mkinitrd-4.1.9-1 to
satisfy the dependency). Now eth1 starts properly on boot.
Is the proper action to mark this as a dup of 112824? Also that bug
is listed as an RFE, but it seems like it ought to be a bugfix and
rolled out as an update.
mass update for old bugs:
Is this still a problem in the 2.6.9 based kernel update ?
Works perfectly in FC3.
