Hello martian experts,
I want to shed some more light on the issue raised by Bjorn.
As I wrote last Friday, I have a similar Problem with the PCMCIA code on
two different laptops.
One has a OpenSuSE 10.0 with kernel 2.6.26.3 and 2.6.28.1.
The other one has OpenSuSE 11.1 with the 2.6.27.21-pae kernel as Bjorn.
There exists a parallel installation of a Linpus Linux on it with a
2.6.25.x kernel and a 2.6.28.1 and 2.6.29.3.
So here are my observations:
1.) On 2.6.25.x I get a "IRQ nobody cared" message, following a
disabling of the IRQ used by the modem.
This results in a "No modem found" message by wvdial.
2.) Under 2.6.26.3 everything works fine, modem gets IRQ 3 and IO-Port
0x2f8 and com port 0x100.
3.) Under 2.6.28.1 Modem can dial and receives "CONNECT 50xxx NoECC"
message from ISP, but immediately
afterwards it hangs up.
Here the IRQ is 3 and IO-port is 0x32f8 and com port 0x100.
The same situation hold true for 2.6.29.3 kernel.
The only difference is the IO port address. As the same problem exists
on different machines, I think the driver code itself can be ruled out
as the source of the problem, as otherwise dialing should also not work.
I will take a look at the code of pppd, whether it tries to access the
hardware directly (I don't believe that) or where the problem could come
from.
Bjorn can you still check what IO ports your modem used when it was
still working, and what are the addresses now?
Regards,
Joern
