Detection of USB devices by the kernel is slow enough. We need to keep trying for a while (default: 5s seconds, controlled by roottimeout=<seconds>) and sleep between each attempt (default: one second, rootdelay=<seconds>).
Fix is based on https://git.yoctoproject.org/cgit.cgi/poky/commit/meta/recipes-core/initrdscripts/initramfs-framework/rootfs?id=ee6a6c3461694ce09789bf4d852cea2e22fc95e4 Signed-off-by: Naveen Saini <naveen.kumar.sa...@intel.com> --- .../initramfs-framework/dmverity | 64 +++++++++++-------- 1 file changed, 37 insertions(+), 27 deletions(-) diff --git a/recipes-core/initrdscripts/initramfs-framework/dmverity b/recipes-core/initrdscripts/initramfs-framework/dmverity index bb07aab..888052c 100644 --- a/recipes-core/initrdscripts/initramfs-framework/dmverity +++ b/recipes-core/initrdscripts/initramfs-framework/dmverity @@ -10,33 +10,43 @@ dmverity_run() { . /usr/share/misc/dm-verity.env - case "${bootparam_root}" in - ID=*) - RDEV="$(realpath /dev/disk/by-id/${bootparam_root#ID=})" - ;; - LABEL=*) - RDEV="$(realpath /dev/disk/by-label/${bootparam_root#LABEL=})" - ;; - PARTLABEL=*) - RDEV="$(realpath /dev/disk/by-partlabel/${bootparam_root#PARTLABEL=})" - ;; - PARTUUID=*) - RDEV="$(realpath /dev/disk/by-partuuid/${bootparam_root#PARTUUID=})" - ;; - PATH=*) - RDEV="$(realpath /dev/disk/by-path/${bootparam_root#PATH=})" - ;; - UUID=*) - RDEV="$(realpath /dev/disk/by-uuid/${bootparam_root#UUID=})" - ;; - *) - RDEV="${bootparam_root}" - esac - - if !
