OpenWrt 22.03.0-rc2 and rc3 are causing on a Fritzbox 7412 bootloops due to a misdetected flash chip.
Until OpenWrt 22.03.0-rc1 the boot log states
[ 8.397735] nand: device found, Manufacturer ID: 0x98, Chip ID: 0xf1
[ 8.402654] nand: Toshiba NAND 128MiB 3,3V 8-bit
[ 8.407264] nand: 128 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 64
but beginning with OpenWrt 22.03.0-rc2 the boot log states
[ 8.420923] nand: device found, Manufacturer ID: 0x98, Chip ID: 0xf1
[ 8.425851] nand: Toshiba TC58NVG0S3HTA00 1G 3.3V 8-bit
[ 8.431069] nand: 128 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 128
The chip soldered on my device reads as Toshiba TC58BVG0S3HTA00, which has a different page organisation and it complains about fixable bit-flip detection and afterwards about uncorrectable ECC errors when it's handled like the N. Dunno yet how to fix, but haven't investigated further...
But rc2 and rc3 are not released yet, so...
