This bug is awaiting verification that the linux-oem-6.14/6.14.0-1012.12 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.14' to 'verification-done- noble-linux-oem-6.14'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.14' to 'verification-failed- noble-linux-oem-6.14'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Boot up the Intel Birch Stream SoC machine which has multiple devices need to load i801_smbus module 2. There should be no such error in dmesg sysfs: cannot create duplicate filename '/bus/platform/devices/iTCO_wdt' [Where problems could occur] It removes the watchdog feature for Intel Birch Stream SoC in the driver, won't affect other platforms, and should not introduce any regressions.
