Description Kjartan Maraas 2004-11-17 17:41:11 UTC

Description of problem:
If I shut down my laptop without stopping the pcmcia service the
machine enters an infinite loop where the airo driver spews the
console with a lot of diagnostics and messages saying it's waiting for
the device to become free and that the use count is still 1. I also
see the following when doing service pcmcia start/stop:

[root@localhost wireless]# service pcmcia stop
Shutting down PCMCIA services: ERROR: Module pcmcia_core is in use by
yenta_socket
done.
[root@localhost wireless]# service pcmcia start
Starting PCMCIA services: cardmgr[3746]: open_sock(socket 2) failed:
Bad file descriptor
cardmgr[3746]: watching 2 sockets
done.
[root@localhost wireless]#

[root@localhost wireless]# lsmod |grep airo
airo_cs                 7237  0
airo                   64225  1 airo_cs
ds                     16965  5 airo_cs

I saw the Use count = 1 message using madwifi too. Maybe it's a
refcounting problem in the pcmcia subsystem itself? Could be that both
drivers do the same thing wrong of course...

Latest offender is vmware with a vmnet device spewing these warnings.

Comment 4 Dave Jones 2005-07-15 18:35:24 UTC

An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.

This bug has been automatically closed as part of a mass update.
It had been in NEEDINFO state since July 2005.
If this bug still exists in current errata kernels, please reopen this bug.

There are a large number of inactive bugs in the database, and this is the only
way to purge them.

Thank you.
