ne2000 (ISA) & test11+

ne2000 (ISA) & test11+

[Taco IJsselmuiden]

Hi All,

First off: I wish everyone a very happy and coded 2001.
Second: I'm having problems loading my ne2000 (ISA) card as a module since
test11 (test10 + 2.2.17 works perfectly. Haven't tried 2.2.18...):

When loading the module with 'modprobe ne io=0x360 irq=4' it says:

/lib/modules/2.4.0-prerelease/kernel/drivers/net/ne.o: init_module: No
such device or address
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters
/lib/modules/2.4.0-prerelease/kernel/drivers/net/ne.o: insmod
/lib/modules/2.4.0-prerelease/kernel/drivers/net/ne.o failed
/lib/modules/2.4.0-prerelease/kernel/drivers/net/ne.o: insmod ne failed

When using test10 or 2.2.17 it works ;)
I'm I just being plain stupid (as in: did I miss something...), or is
something wrong ??

system specs:
2.4.0-prerelease
debian woody
gcc version 2.95.2 20000220 (Debian GNU/Linux)
GNU Make version 3.79.1, by Richard Stallman and Roland McGrath.
GNU ld version 2.10.91 (with BFD 2.10.1.0.2)
insmod version 2.3.23
tune2fs 1.19, 13-Jul-2000 for EXT2 FS 0.5b, 95/08/09

Cheers,
Taco.
P.S.: I'm not linux-kernel, so please cc me (I read web-archives...)

ditto for myself since i started using new SMP machine sometime around
2.4.0-test8 or so.

the modprobe works the second time (and subsequently) when i run it by
hand after boot scripts finish.

i've tried all kinds of combinations of insmod/modprobe/isapnp etc
with no luck. wouldnt mind tracking this annoyance down.

boot log:

[finish boot]

then modprobe by hand:

Ok, I suspect the phasing out of check_region(...) is responsible
here.  In test10 and older, check_region() wasn't done if an explicit
i/o address was supplied - this was to accomodate the now rarely used
reserve= bootprompt which dates back to before modules existed.

Since ne.c doesn't allow modular autoprobing, there was always an i/o
address present, and hence you could still load the module even if
there was a potential i/o space conflict.

In test11 and newer, check_region() is gone and an unconditional
request_region() takes place, which will not allow any i/o space
conflict.  In your case, 0x360 is suspect since a ne2000 is 0x20
wide in i/o space and you are probably bumping into either:

0376-0376 : ide1
0378-037a : parport0

Check your /proc/ioports, and relocate your ne card as appropriate.

Paul.

Note in the failed case you have no line that says "ne.c: ISAPnP reports..."
which is the clue here.  If you supply an i/o address, such as....

> from etc/modules.conf:
> 
> alias eth1 ne
> options ne irq=5 io=0x220

then no PnP is involved in the probing at all.  If you are relying on the
PnP part of the probe to activate your card, but it isn't being used....
OTOH, if you *don't* supply an I/O address, then the PnP part of the probe
will be used; you will see the "ne.c: ISAPnP reports..." message, and all
should be well.  So try deleting your options line (for 2.4.x kernels).

There is also a possibility of an i/o conflict - as the other person
had at 0x360 now that check_region is gone - in your case maybe with 
the i/o regions isapnp itself reserves, since your ne2k is way down
low at 0x220. In fact isapnp assumes that NE2000 cards will start
between 0x280 and 0x360 - and avoids this region because of that.

Paul.

Yep, that does the trick ;)
Thanks.

<pondering>
Hmm, so all this time I've had an io-conflict ...
Maybe my box will get even more stable now ;))

Cheers,
Taco.
