View Full Version : Itex ADSL card with Linux

30-03-2002, 02:51 PM
I've now spent a week trying to get a Dynalink AHL-110 to work with Linux. I've followed the instructions in http://www.ahs- png.org/lintech/linux_hints_tips/ADSL/ but have struck a problem.

When I 'insmod itex1577-2.4.2.o' the driver correctly finds the card and it's settings but then segmentation faults. The output of which is at the end of this message. The fault happens after retrieving the MAC address but before reporting the chip number.

If I remove the card from the machine insmod doesn't segmentation fault (it doesn't load of course).

The only thing I can find that hints at a possible problem is that depmod says there are unresolved symbols in itex1577-2.4.2.o. Or is this OK as others seem to get this as well.

The machine is an old Pentium 166, but presumeably this isn't a problem.

I've emailed Itex about this and got the latest drivers off them but still can't solve it. I've tried so many different kernel configurations that I'm sure that's not it.

Any help, hints, suggestions greatly appreciated. Please, I'm getting desperate.

You could try adding insmod itex1577-2.4.2 to your /etc/rc.d/local and rebooting. This will try and load the module on startup and may solve your problem.

After the module is loaded I think it's safe to remove insmod itex* from your /etc/rc.d/local file.

No go with rc.local, exactly the same result.

Thanks for the suggestion anyway.

I suspect that the board has a default 'membase' which is beyond your physical memory.

An address of e4000000 is *way* up --- nearly 4GB.

Try giving a 'membase=0xsomething_in_your_memory_space' argument to the insmod command.

This is based on my extensive ignorance of ADSL. I have had a few segmentation errors in my time though. It means that a piece of code is trying to access memory which is either non-existent, or not allowed to the user.

The other idea I have just had --- to use insmod, you need to be root, that is, have privilege. That could be your problem. The memory alocationb would be illegal for a 'user'. Loading from rc.local would cure that though (it is run at each boot, while the system is in single-user [root] mode).

Bugger, it doesn't understand membase. For:

insmod -f itex1577-2.4.2.o membase=0x0e400000

I get:

itex1577-2.4.2.o: invalid parameter: parm_membase

Nevermind. Thanks for the suggestion anyway.

Just to prove I don't really know too much about building a linux kernel... /sbin/insmod has not been recompiled with my kernel rebuilds.

Is this correct? Should it have been? It could certainly explain some problems if it's supposed to be.

I have ADSL modem Alcatel SpeedTouchPC (iTex i90388)
I use module itex1422-2.4.2-2.o and Linux RedHat7.1 (kernel 2.4.2-2)
module correct install, pppoe starting and connecting, internet work....
