I am using rh 7.3 and 9.0 with kernels 2.4.7-10 and 2.4.20-8 I am adding a 3rd party PCI card from Modicon. It is a Modbus Plus card that communicates over a token ring network to other Modbus Plus devices.

I have used this card with other HP machines successfully. I used to get HP xw4000 workstations and install our application and the card with no errors.

HP has again changed the computer to a xw4100. Now with the same redhat installation and kernel the machine locks with the keyboard blinking after about 12 hours.

The redhat 7.3 machines have no obvious errors in the dmesg or messages output.
But, the redhat 9.0 gives the attached error below.

Can anyone decipher the conflict or is the output to general to point it out?

I have attached the lspci and dmesg outputs for reference.

Unfortunately, Modicon will provide no assistance. They only support drivers for Windoze and as soon as I mentioned Linux our conversation ended. I dont believe this is a driver or module issue since our module and driver was successful in other computers.

Any help or advice is appreciated. Thanks
