Public bug reported: I'm validating latest 6.11 kernel on Qualcomm RB3Gen2 (https://www.thundercomm.com/product/qualcomm-rb3-gen-2/) and noticed there is basically no UART output at all, even with earlycon set.
Looking at the kernel config the issue seems to be that all clocks and uart drivers are set as module, which is loaded a bit too late in the boot process. ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2083559 Title: Lack of UART boot output on rb3gen2 even with earlycon To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2083559/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
