Description Need Real Name 2001-05-09 23:05:50 UTC 
Description of Problem:
  I have an aironet 4800 turbo ds card that works fine w/ the standalone 
pcmcia-cs (both w/ 2.2/2.4 kernels) (dell 5000e) However w/ rh7.1 and the 
kernel subsystem I get all sorts of dire warnings on enter : (log file attached).
On exit I get a kernel panic and the system freezes (I can shut down normally 
however... ) I am attaching a log file of the "dire warnings" but not of the kernel 
panic as I'd rather not reproduce that. (I cleaned my system then), but will if you 
guys feel its important ..


How Reproducible:
All the time

Steps to Reproduce:
1. boot up w/ aironet card in or standard enet card
2. remove standard enet card and insert aironet card
3. read /var/log/messages
4. remove aironet card 
Actual Results:
 kernel panic!

Expected Results:
 Happiness for one's no longer connected to the net dell5ke :)

Can you check if you are using the airo_cs or the aironet4500_cs driver ?
And could you try the other one ?
Comment 3 Arjan van de Ven 2001-05-16 17:24:11 UTC 
An other reporter confirmed that changing to the airo_cs driver fixed the
problem. For the next version of kernel-pcmcia-cs, this will become the default
for your card. Could you edit /etc/pcmcia/config and change this ? That should
fix your problem.
Comment 4 Aleksey Nogin 2001-07-31 16:17:14 UTC 
Using airo_cs driver with kernel-2.4.3-12.i686 causes a new set of problems -
after doing one or two couple of cardctl eject/cardctl insert, I would see a
kernel oops and the system would get into some rather weird state, although some
of the shutdown scripts would still work somewhat.

I didn't notice this problems and reported in bug 40552 that airo_cs was OK for
me since until a few days ago I only used RH7.1+aironet card on my desktop,
where I never tried unplugging the card (also, desktop is SMP and is running SMP
kernel, so things may be different there - not that I want risk testing that :-) ).

However, using the kernel-2.4.6-3.1 and kernel-pcmcia-cs-3.1.27-5 from Rawhide
seems to solve all my problems.

Sorry, didn't mean to change the status.
Comment 6 Aleksey Nogin 2002-05-01 16:06:36 UTC 
I believe this problem no longer exists in 7.2
