Package: initramfs-tools Version: 0.130 Severity: normal Dear Maintainer,
after upgrading from jessie to stretch and rebooting, I got a blank screen. Figured out the system was waiting for the hard disk passphrase ("Please unlock disk ...." prompt). After entering the password blindly, the system booted successfully. Using "break=top" and running scripts manually, I found out that the screen went black when running /scripts/init-top/udev. Disabling modesetting via kernel command line made the prompt visible, but caused issues later when starting X, so it's not a solution. Finally, I found out that the fbcon module was missing from the initramfs, and adding it to /etc/initramfs-tools/modules solves the issue. This is on a thinkpad x201s with CPU-integrated intel graphics (i915 driver). Best Regards, Jan -- Package-specific info: BOOT_IMAGE=/vmlinuz-4.11.4 root=/dev/mapper/ssd1-root64 ro intel_iommu=on,igfx_off apparmor=1 security=apparmor vsyscall=emulate quiet
