on slack 12.1 pcmcia doesn't shut down

zux · 05-20-2008, 08:57 AM

I have a 3G modem pluged in a pci to pcmcia card, all works well except for shudown or reboot. every time it hangs on Shuting down pcmcia: cards.
i looked over the rc.pcmcia script and found that it hangs when the command:

Code:

 /sbin/pccardctl eject

is executed.

Any ideas?

Don't fully understand your hardware setup but.... with/after connecting the 3G modem to the pcmcia card do you have to load any modules or similar command in rc.local. If so then using the shutdown -> rc.local try unloading/stopping whatever you have started during boot. As the local shutdown is run before tearing down the pcmcia card it may proceed properly (note you may need a 'sleep 5' as the last step to give time for the reverse process to complete before trying to eject the card.

I think it loads some modules automatically, this doesn't happen if the card was never pluged in. but if I pull it out before shutdown it still hangs. I'll post back from work

when I plug in the card there are 3 modules loaded:

Code:

option                 12928  0 
usbserial              33384  1 option
ssb                    32516  0

probably by udev.
after unloading those modules it shuts down normally.

in rc.pcmcia:

Code:

 echo -n "Shutting down PCMCIA services: "
                echo -n "cards "
                /sbin/pccardctl eject
                MODULES=`/sbin/lsmod | grep "pcmcia " | awk '{print $4}' | tr , 
' '`
                for i in $MODULES ; do
                        echo -n "$i "
                        /sbin/modprobe -r $i > /dev/null 2>&1
                done

so the pcmcia stop script doesn't even try to unload them + unloading of the modules is done after the pccardctl eject

from man pccardctl:

Code:

 eject
           Notify  all  client  drivers that this card will be ejected,
           then cut power to the socket.

so this is where they should be unloaded, but they don't.

added

Code:

/sbin/modprobe -r option
/sbin/modprobe -r usbserial

in /etc/rc.d/rc.local_shutdown.
that fixed it.

is this a bug? should i report it?

I also added

Code:

killall wvdial

becouse it was using the module option, don't know if that was realy neede.

Just installed 12.1 and had the same problem.

I also had it in 12.0. I believe I changed the order of running of the shutdown scripts. I will post what I did.

My pcmcia card is basically a usb hub which I only ever have a mouse plugged in.

In 12.0 all I thought I did was to move rc.pcmcia to be called earlier in rc.0/rc.6. I can't remember doing anything else though I must have done it doesn't make sense that moving it to be called earlier in the shutdown process would fix the problem.

Anyway that doesn't work for 12.1. So the only way I could overcome the problem was to move rc.pcmcia down to after the section that kills all processes!!!!!

What I did determine though that with the mouse plugged in rc.pcmcia hangs at

Code:

/sbin/pccardctl eject

whereas if the mouse is not plugged in the rc.pcmcia doesn't hang.

I'll continue to look at this to find what process is causing the card to be busy - obviously something to do with the mouse.
