Bug: 2.4.0-test12 w/ PCMCIA on ThinkPad: KERNEL: assertion(dev->ip_ptr==NULL)failed at dev.c(2422):netdev_finish_unregister

Bug: 2.4.0-test12 w/ PCMCIA on ThinkPad: KERNEL: assertion(dev->ip_ptr==NULL)failed at dev.c(2422):netdev_finish_unregister

[Thomas Hood]

2.4.0-test12 compiled on an IBM ThinkPad 600 51U (Pentium II)
with PCMCIA support.  Same behavior with Linus PCMCIA and 
Hinds PCMCIA.  I have a Xircom modem/ethernet card which
works correctly using the serial_cs, xirc2ps_cs, ds, i82365 
and pcmcia_core modules; however when I try to "cardctl eject"
or "reboot" I get first,

"KERNEL: assertion(dev->ip_ptr==NULL)failed at
dev.c(2422):netdev_finish_unregister"

(not exact since I had to copy it down on paper ... doesn't
show up in the logs) then a perpetual series of:

"unregister_netdevice: waiting for eth0 to become free. Usage count =
-1"

messages every five seconds or so.  "ps -A" reveals that
modprobe is running; it can't be killed even with "kill -9".
The "ifconfig" command locks up.

With recent kernels, ThinkPad 600 won't resume for two minutes after suspend

[Thomas Hood]

Hi.

With recent kernels, my ThinkPad 600 won't resume for two minutes
after it is suspended.  When the Fn key is pressed the machine
starts up, the CD-ROM scans, the screen backlight turns on,
and the APM light flashes.  But then it just stays like that
instead of restarting the CPU; it is completely hung, although
the APM light continues to flash.  If I wait more than about
two minutes with the machine suspended, however, then everything
resumes normally.

I have been running Linux for two years.  This never happened
before a couple weeks ago when I upgraded to kernels 2.2.18 and
then 2.4.0 .  I have since tested kernel 2.2.17 and see the
same problem.  Do I have a hardware problem, or might something
have changed in the kernel that could lead to this behavior?

I have 600X and 2.2.1[6-8] work just fine.
the only silly thing is I have to switch to text console before sspending
the laptop, otherwise after resume the X looses keyboard and you can
only login from network :(

Bug: 2.4.0 w/ PCMCIA on ThinkPad: KERNEL: assertion(dev->ip_ptr==NULL)failed at dev.c(2422):netdev_finish_unregister

[Thomas Hood]

Dear l-k.

I'm still having this problem with kernel 2.4.0:

Conditions:
Linux 2.4.0 compiled on an IBM ThinkPad 600 51U (Pentium II)
laptop with PCMCIA support.  Same behavior with integral kernel
PCMCIA, modular kernel PCMCIA and modular Hinds PCMCIA.  System
is Progeny Debian beta II.

I have a Xircom modem/ethernet card which works correctly using
the serial_cs, xirc2ps_cs, ds, i82365 and pcmcia_core modules;
however when I try to "cardctl eject" or "reboot" I get first,
   "KERNEL: assertion(dev->ip_ptr==NULL)failed at
    dev.c(2422):netdev_finish_unregister"
(not exact since I had to copy it down on paper ... doesn't
show up in the logs) then a perpetual series of:
   "unregister_netdevice: waiting for eth0 to become free.
    Usage count = -1"
messages every five seconds or so.  "ps -A" reveals that
modprobe is running; it can't be killed even with "kill -9".
The "ifconfig" command locks up.  Shutdown won't complete
so I end up having to use SysRq-S-U-B to reboot.

This problem only occurs if the Xircom card is connected to
the Ethernet (in which case it is configured using DHCP).
If the card is left unconnected to the network, the problem
does not occur---the card can be ejected.

[BUG] Shutting down PCMCIA driver in Linux 2.4.1, "Trying to free nonexistent resource <000003e0-000003e1>"

[Thomas Hood]

I get this message when shutting down Linux with 2.4.1 kernel,
kernel PCMCIA support compiled as a module.

---------------------------------------------------------------------------------

$ cat /proc/ioports
...
03e0-03e1 : i82365
...
$ sudo reboot
(reboot)
$ grep 3e0 /var/log/messages
Feb  4 18:13:44 thanatos kernel: Trying to free nonexistent resource <000003e0-000003e1>

----------------------------------------------------------------------------------

IIRC, during the shutdown sequences the "Trying ..." message appears just
after the words "Shutting down PCMCIA card services: cardmgr modules".

It's harmless. You can ignore it. It'll be cleaned up, but there are far 
more interesting bugs to squash first :)
