How to Fix: Why does lspci stop with error -2?

                The primary cause of this error is a compatibility issue between the `lspci` command and the libkmod library used by the Linux kernel for PCIe device management. The libkmod library has a bug that causes it to fail loading resources with an error code of -2 when dealing with certain types of PCIe devices.Another potential cause could be a misconfigured or corrupted PCIe device driver, which may prevent the `lspci` command from functioning properly.

            🚀 How to Resolve This Issue

                Updating libkmod library

                    Step 1: Update the Linux kernel to the latest version using the package manager (e.g., `sudo apt-get update && sudo apt-get upgrade`). This may resolve compatibility issues with libkmod.Step 2: If updating the kernel is not possible, try updating the libkmod library separately by running `sudo apt-get install libkmod2:amd64`.



                Reconfiguring PCIe device drivers

                    Step 1: Disable and re-enable the problematic PCIe device using the `lspci -v -D` command. This may help resolve issues with the device driver.Step 2: If disabling and re-enabling the device does not work, try blacklisting the device in the kernel's configuration files (e.g., `/etc/modprobe.d/blacklist.conf`). Add a line similar to `blacklist: 03:00.0` to blacklist the device.


            ✨ Wrapping Up
            To troubleshoot and fix the 'lspci: Unable to load libkmod resources: error -2' issue, try updating the libkmod library or reconfiguring PCIe device drivers. If these steps do not resolve the issue, further investigation may be necessary to identify the root cause of the problem.
