CRC: len=0xf080, cal=0x27ff5de9, img=0x27ff5de9, match! [Test Case]: Deploy Focal/Arm64-Generic to a ThunderX2 in the MAAS (Metal As a Service) provisioner. Using MAAS version: 2.9.3~beta1 (9197-g.afe92bb63) via a snap, the daily focal image appears to be 20210811 From the kernel teams standpoint this kernel in the initrd, did pass SRU testing before its release. [Fix]: N/A [Regression]: Probably No (From Kernel Viewpoint) this could possibly be caused by something other than kernel.
