Troubleshooting

The boot time error messages and solutions are stated as clearly as possible. If you exhaust all possible solutions without solving the problem, please contact our technical support team for more help.

Error msg:

More than 4 Moxa Smartio/Industio family boards found. Fifth board and after are ignored.

Solution:

To avoid this problem, unplug the 5th, 6th, etc., boards. The Moxa driver supports a maximum of 4 boards.

Error msg:

Request_irq fail, IRQ address may conflict with another device.

Solution:

Other PCI or ISA devices are using the assigned IRQ. If you are not sure which device is causing the problem, check /proc/interrupts to find a free IRQ that can be assigned to the Moxa board.

Error msg:

Board #: C1xx Series(CAP=xxx) interrupt number invalid.

Solution:

Each port within the same multiport board shares the same IRQ. Set one IRQ (IRQ not
