The error message “LinuxACPI: I\/O resource it87 [0x295-0x296] conflicts with ACPI region IP__ [0x295-0x296]” indicates that there is a resource conflict between two devices in your system. This can cause problems with system stability and performance.<\/p>\n

Here’s how to resolve this error:<\/p>\n

    \n
  1. Open a terminal window on your Linux system.<\/li>\n
  2. Use the lspci<\/code> command to identify the device causing the resource conflict. For example:<\/li>\n<\/ol>\n
    \n
    <\/div>\n
    lspci -v
    \n<\/code><\/div>\n<\/div>\n

    This will display a list of all devices in your system. Look for the device that is using the resource range mentioned in the error message, in this case it87 [0x295-0x296]<\/code>.<\/p>\n

      \n
    1. Once you have identified the device, you can try disabling it temporarily to see if the resource conflict goes away. You can do this by unloading the kernel module associated with the device using the rmmod<\/code> command. For example:<\/li>\n<\/ol>\n
      \n
      <\/div>\n
      sudo rmmod it87
      \n<\/code><\/div>\n<\/div>\n

      This will unload the kernel module associated with the it87<\/code> device.<\/p>\n

        \n
      1. If unloading the kernel module resolves the resource conflict, you can prevent the module from being loaded automatically on boot by adding it to the \/etc\/modprobe.d\/blacklist.conf<\/code> file. For example, add the following line to the file:<\/li>\n<\/ol>\n
        \n
        <\/div>\n
        blacklist it87
        \n<\/code><\/div>\n<\/div>\n

        This will prevent the it87<\/code> kernel module from being loaded on boot.<\/p>\n

          \n
        1. If disabling the device is not an option, you may need to modify the ACPI tables to resolve the resource conflict. This requires advanced knowledge and should be done with caution, as it can potentially cause system instability. You can refer to the ACPI documentation and consult with experts for guidance on modifying the tables.<\/li>\n<\/ol>\n

          By resolving the resource conflict, you can improve the stability and performance of your Linux system.<\/p>\n","protected":false},"excerpt":{"rendered":"
