This release reverts to an earlier version of the Linux kernel to resolve two issues being reported in 6.12.9. It also includes a 'curl' security update and corner case bug fix. We'd appreciate your feedback before releasing it as 6.12.10 This thread is perfect for quick questions or comments, but if you suspect there will be back and forth for your specific issue, please start a new topic. Be sure to include your diagnostics.zip. Upgrade steps for this release As always, prior to upgrading, create a backup of your USB flash device: "Main/Flash/Flash Device Settings" - click "Flash Backup". Update all of your plugins. This is critical for the Connect, NVIDIA and Realtek plugins in particular. If the system is currently running 6.12.0 - 6.12.6, we're going to suggest that you stop the array at this point. If it gets stuck on "Retry unmounting shares", open a web terminal and type: umount /var/lib/docker The array should now stop successfully. If you have a recent release or Unraid Connect installed: Open the dropdown in the top-right of the Unraid webgui and click Check for Update, then press More options and switch to the Next branch. You may be prompted to sign in to access the Next branch. Select the appropriate version and choose "View changelog to Start Update". More details in this blog post If you are on an earlier version: Go to Tools -> Update OS and switch to the "Next" branch. If the update doesn't show, click "Check for Updates" Wait for the update to download and install If you have any plugins that install 3rd party drivers (NVIDIA, Realtek, etc), wait for the notification that the new version of the driver has been downloaded.

It also includes a 'curl' security update and corner case bug fix. Known issues Out of date plugins Out of date plugins can cause problems, we recommend they be kept current. Call traces and crashes related to macvlan If you are getting call traces related to macvlan (or any unexplained crashes, really), as a first step we recommend navigating to Settings > Docker, switching to advanced view, and changing the Docker custom network type from macvlan to ipvlan. This is the default configuration that Unraid has shipped with since version 6.11.5 and should work for most systems. Note that some users have reported issues with port forwarding from certain routers (Fritzbox) and reduced functionality with advanced network management tools (Ubiquity) when in ipvlan mode. If this affects you, see the alternate solution available since Unraid 6.12.4. Network problems due to jumbo frames If you are having network issues of any kind, confirm that you have not enabled jumbo frames. Navigate to Settings > Network Settings > eth0 and confirm the Desired MTU is 1500. For more information see the Fix Common Problems warning for jumbo frames. Problems due to Realtek network cards Upgraded kernel fixes the deadlock issue with jumbo frames and the in-tree Realtek 8125 driver. However, we still recommend following the advice above regarding jumbo frames. If you continue to have network stability issues and Tools > System Devices shows that you have a Realtek ethernet controller, grab the part number shown and search Community Apps to see if there is a Realtek vendor-supplied driver plugin for that device. For more information, see the support page for Realtek driver plugins. Other issues? We highly recommend installing the Fix Common Problems plugin as it will warn you of common configuration problems. If you are having other crashes or stability issues, navigate to Settings > Syslog Server and enable Mirror syslog to flash. This will cause additional wear and tear on you USB flash boot device but is useful in the short term for gathering logs after a crash. After the next reboot, navigate to Tools > Diagnostics and download your anonymized diagnostics (as of 6.12.5, diagnostics automatically include logs that were mirrored to the flash drive). Finally, start a new topic and provide all the details of the issue. Once the issue is resolved, be sure to disable Mirror syslog to flash. Rolling back Be aware that rolling back to an earlier release will make your system vulnerable to the Docker security issues and potential data loss scenario mentioned in Upgrade notes. If rolling back earlier than 6.12.9, also see the 6.12.9 release notes. Changes vs. 6.12.9 Bug fixes and improvements Resolve issues mounting remote SMB shares via the Unassigned Devices plugin.
