The new Tumbleweed snapshot 20210317 release solves my issue with the failing RPI4 USB boot. I guess this is the part of that release that solves my issue: - Update config files: Set reset-raspberrypi as builtin (bsc#1180336) This driver is needed in order to boot through USB. Ideally the kernel module should be selected by dracut, but it's not. So make it builtin until the relevant dracut fixes are available. Still, with each update that creates a new initramfs, I see errors like: dracut-install: Failed to find module 'crc32c' dracut: FAILED: /usr/lib/dracut/dracut-install -D /var/tmp/dracut.IvY0Au/ initramfs -H -N i2o_scsi --kerneldir /lib/modules/5.11.6-3-default/ -m crc32c dracut: *** Including modules done *** dracut-install: Failed to find module 'bcm2835-sdhost' dracut: FAILED: /usr/lib/dracut/dracut-install -D /var/tmp/dracut.IvY0Au/ initramfs -N i2o_scsi --kerneldir /lib/modules/5.11.6-3-default/ -m sdhci_iproc bcm2835-sdhost bcm2835_dma mmc_block dwc2 Is that a known issue? I cannot seem to find much about it. -- Paul.
