Commit3cf2782906(support/testing/infra/emulator.py: update pre-built kernels) bumped the default kernels used by the testing infra. However, the newer armv7 kernel (at least) no longer has support for lz4-compressed squashfs filesystems. This breaks the squashfs test: Filesystem uses "lz4" compression. This is not supported List of all partitions: 1f00 131072 mtdblock0 (driver?) 1f01 32768 mtdblock1 (driver?) b300 2048 mmcblk0 driver: mmcblk No filesystem could mount root, tried: squashfs Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,0) Updating the kernel again is a little bit cumbersome, while fixing the actual test is relatively trivial, so this is what we do: we switch over to lzo, which is supported by the new kernel: # zcat /proc/config.gz |grep SQUA CONFIG_SQUASHFS=y CONFIG_SQUASHFS_ZLIB=y # CONFIG_SQUASHFS_LZ4 is not set CONFIG_SQUASHFS_LZO=y # CONFIG_SQUASHFS_XZ is not set While at it, also drop the superfluous line disabling gzip compression: it is part of a choice, so enabling one (lzo here) forcibly disables the others (of which gzip).
