Red Hat Bugzilla – Bug 139709
airo_cs: infinite loop on shutdown
Last modified: 2015-01-04 17:12:22 EST
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
[root@localhost wireless]# service pcmcia start
Starting PCMCIA services: cardmgr: open_sock(socket 2) failed:
Bad file descriptor
cardmgr: watching 2 sockets
[root@localhost wireless]# lsmod |grep airo
airo_cs 7237 0
airo 64225 1 airo_cs
ds 16965 5 airo_cs
pcmcia_core 59913 3 airo_cs,ds,yenta_socket

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.
