Hello Diederik, Yes it works with initramfs-tools version 0.140 from bullseye on USB.
I have tested : https://raspi.debian.net/verified/20210210_raspi_4_buster.img.xz It boots on USB. But after upgrade, kernel updated, it cannot boot any more. https://raspi.debian.net/daily/raspi_4_buster.img.xz It cannot boot on USB. https://raspi.debian.net/verified/20210413_raspi_4_bullseye.img.xz It boots on USB. Upgrade, upgrade kernel, update-initramfs is called. It still boots. https://raspi.debian.net/daily/raspi_4_bullseye.img.xz It boots on USB. Upgrade. cryptsetup and lvm2 is installed, update-initramfs is called. It still boots. So I'll used initramfs-tools from bullseye. Thanks a lot. -- David ----- Mail original ----- > On vrijdag 23 april 2021 16:27:05 CEST Vorak David Hoeung wrote: > > Have you any idea ? > > You need a newer image which contains initramfs-tools version 0.140, > where the > reset_raspberrypi module gets included.
