Yes, emphasis on should. Just to clarify, if you reboot it works and cold start works as well if power was off long enough? > [=C2=A0=C2=A0=C2=A0 0.000000] Linux version 5.8.0-rc6 (oe-user@oe-host) (= x86_64-poky-linux-gcc (GCC) 10.1.0, GNU ld (GNU Binutils) 2.34.0.20200220) = #1 SMP Sat Jul 25 03:55:25 UTC 2020 > [=C2=A0=C2=A0=C2=A0 0.000000] Command line: BOOT_IMAGE=3D/bzImage ima_pol= icy=3Dtcb > apic=3Ddebug ip=3Ddhcp raid=3Dnoautodetect console=3DttyS0,115200 > root=3D/dev/nfs nfsroot=3D192.168.1.100:/nfs/vxc,hard,tcp,intr,v3 rootwait > nfsrootdebug The working dmesg and the failing console log are hard to compare because the latter does not contain debug level printks.
