Hi, reinstalled using https://dl.armbian.com/odroidxu4/Buster_legacy running kernel Linux odroidxu4 4.14.180-odroidxu4 #16 SMP PREEMPT Wed May 20 19:58:06 CEST 2020 armv7l GNU/Linux still the same issue. updated diagnosis I think it has something to do with the empty emmc slot: SD Card: cat /sys/kernel/debug/mmc1/ios clock: 200000000 Hz actual clock: 200000000 Hz vdd: 16 (2.8 ~ 2.9 V) bus mode: 2 (push-pull) chip select: 0 (don't care) power mode: 2 (on) bus width: 2 (4 bits) timing spec: 6 (sd uhs SDR104) signal voltage: 1 (1.80 V) driver type: 0 (driver type B) MMC slot: clock: 0 Hz vdd: 7 (1.65 - 1.95 V) bus mode: 2 (push-pull) chip select: 0 (don't care) power mode: 1 (up) bus width: 0 (1 bits) timing spec: 0 (legacy) signal voltage: 1 (1.80 V) driver type: 0 (driver type B) but it keeps bouncing between different values: MMC Slot with a different reading: clock: 100000 Hz actual clock: 100000 Hz vdd: 7 (1.65 - 1.95 V) bus mode: 2 (push-pull) chip select: 0 (don't care) power mode: 2 (on) bus width: 0 (1 bits) timing spec: 0 (legacy) signal voltage: 1 (1.80 V) driver type: 0 (driver type B) I tried to swap my 64 gig samsung "pro plus Class 10 U3" card for a more generic Sandisk 64 gig Class 10 UHS 1 card, also no difference..

Hi Igor, thank you for your blazing fast answer! Unfortunately, I can only post once, every 24 hours? I downgraded the kernel via sudo apt-get install armbian-config result: Linux odroidxu4 4.14.150-odroidxu4 #2 SMP PREEMPT Mon Oct 28 08:07:45 CET 2019 armv7l GNU/Linux This seemed to help for like one reboot, the messages are back now.
