The error message "bnx2: eth1: No interrupt was generated using MSI, switching to INTx mode" usually indicates that there is a problem with the interrupt handling for the eth1 network interface on a Linux system.
The "MSI" in the error message stands for "Message Signaled Interrupts", which is a mechanism used by some hardware devices to generate interrupts in a more efficient way than traditional "INTx" interrupts.
If the system is unable to generate MSI interrupts for the eth1 interface, it will fall back to using INTx interrupts instead. This is usually not a problem, but it can result in a slight performance degradation.
There are several possible reasons why the system might be unable to generate MSI interrupts for the eth1 interface:
Hardware issue: There may be a problem with the hardware itself, such as a malfunctioning network card or motherboard.
Software issue: There may be a problem with the device driver or system configuration that is causing the MSI interrupts to fail.
Conflict with other hardware: There may be a conflict with other hardware on the system that is preventing the MSI interrupts from functioning properly.
To troubleshoot this issue, you can try the following steps:
Check the hardware: Make sure that all of your hardware is functioning properly and is compatible with the system.
Check the device driver: Make sure that you are using the latest version of the device driver for the eth1 interface, and that it is compatible with your hardware and system.
Check for conflicts: Make sure that there are no conflicts with other hardware on the system that may be causing the MSI interrupts to fail.
If you are unable to resolve the issue, you may need to seek additional help or guidance from the Linux community or a professional.
