I forced a downgrade of intel-microcode from "" to "", regenerated the initrd images, and now they seems to boot correctly!
So, the problem seems to be with latest intel-microcode? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1882890 Title: Cannot boot initrd.img-4.15.0-106-generic on Ubuntu 16.04 Status in linux package in Ubuntu: Incomplete Bug description: Hi, This morning I applied the latest updates on my Ubuntu 16.04 (kernel 4.15.0-106-generic + intel-microcode 3.20200609.0ubuntu0.16.04.0) and rebooted as usual to boot on the new kernel but the system won't boot: black screen. I tried booting the previous kernel 4.15.0-101 and it seems to be the same : in grub I select the 4.15.0-101 kernel, press enter, a message "Loading initrd..." is printed but nothing else happens. Tried even older kenrel 4.4.0-184-generic : same problem, "Loading initrd...", and nothing happens. I managed to boot a 4.4.0-142-generic, but bluetooth and wifi are non- functionnal. I mounted the /boot partition from a USB rescue drive, and it seems that all the initrd images that got updated this morning are not bootable anymore : - initrd.img-4.15.0-106-generic - initrd.img-4.15.0.101-generic - initrd.img-4.4.0-184-generic I tried regenerating the images with update-initramfs but it's the same : "Loading initrd" message but nothing happens.
