I’m experiencing an issue where my Ubuntu system fails to boot, and it seems to be related to an iwlwifi error concerning an invalid buffer destination. Has anyone encountered this problem and can suggest potential solutions or troubleshooting steps?

I’m really stuck right now with my Ubuntu system. For some reason, it just won’t boot, and I’ve been pulling my hair out trying to figure out what’s wrong. I suspect it has something to do with the iwlwifi driver, as I’ve seen some error messages flashing across the screen that mention an invalid buffer destination related to that before it crashes out on me.

The weird thing is that everything was working fine until I installed some updates a few days ago. The laptop was running smoothly, but after the last update, it started acting up. Now, every time I turn it on, I get this error and can’t get to the login screen or anything. I’ve tried booting into recovery mode, but even there, I can’t seem to do much since the errors keep coming up.

I’ve done a little digging online and found some forums where other people have discussed similar issues with iwlwifi, but the solutions suggested haven’t worked for me. I’ve tried updating the drivers using a live USB, but it’s tricky when you can’t fully boot into the system. I’m not sure if it’s a bug from the recent update or something wrong with my hardware. Honestly, I’m feeling a bit overwhelmed, and I don’t want to lose any data since there’s some important stuff on there.

If anyone has faced a similar issue or has any insights on how to troubleshoot this iwlwifi problem, I’d really appreciate your thoughts! How did you manage to resolve it? Maybe some specific commands or steps I should try while in recovery mode? I’m open to any advice at this point, as I just want my laptop up and running again. Thanks in advance for any help you can offer!

    1. Ubuntu Boot Issue – Help Needed

      Stuck with Ubuntu Boot Issue

      Sounds like you’re having a tough time! Here are some things you can try:

      1. Boot with Previous Kernel Version

      When you start your laptop, hold down the Shift key to bring up the GRUB menu. From there, try booting with a previous kernel version. Sometimes updates mess things up, and rolling back could help.

      2. Using Recovery Mode

      If you can get into recovery mode, you might try a few things:

      • Select root to drop into a shell.
      • Run apt-get update and then apt-get upgrade. Sometimes, reinstalling the kernel can work.
      • Use apt-get remove --purge iwlwifi to remove the driver and then apt-get install iwlwifi to reinstall it.

      3. Check for Errors

      While in recovery mode, you can also check logs to see if anything stands out:

      • Run cat /var/log/syslog | grep iwlwifi to see if there are specific errors.
      • Check dmesg for more insight: dmesg | grep iwlwifi.

      4. Boot from Live USB

      If you have access to another computer, create a Live USB of Ubuntu and boot from it. You can try accessing your file system to back up your data before doing more troubleshooting.

      5. Hardware Check

      Lastly, if the software fix doesn’t work, consider if there could be a hardware issue. Check physical connections or run diagnostics if your laptop supports it.

      Good luck! It can be daunting when things go wrong, but with some patience, you’ll get through this!


    2. The issue you’re facing with your Ubuntu system, particularly relating to the iwlwifi driver and the boot problems after the recent updates, is not uncommon. It sounds like you might be encountering a conflict with the network driver that’s affecting the boot process. In recovery mode, you can attempt to disable the iwlwifi driver to see if that allows you to boot into the system. To do this, boot into recovery mode and choose the ‘Drop to root shell prompt’ option. Once in the shell, you can block the iwlwifi driver using the command echo "blacklist iwlwifi" >> /etc/modprobe.d/blacklist.conf. This will prevent the driver from loading during boot, and may allow you to access your system and troubleshoot further.

      If disabling the driver enables you to log in, proceed to check for any potential issues with the driver or revert to a previous configuration. You can also try reinstalling the driver or rolling back the updates that may have caused the conflict. If you had recent updates through the terminal, consider also executing sudo apt-get remove --purge iwlwifi and then sudo apt-get install firmware-iwlwifi after updating your package list with sudo apt-get update. However, ensure you have your data backed up, either on an external drive or through a live USB, before manipulating system files or drivers. If you can’t access your data through these means, consider using a live session of Ubuntu to mount your drives and safely copy your important files elsewhere.
