We're seeing an ext4 issue previously reported at https://lore.kernel.org/lkml/20190514092054.GA6949@osiris. [ 1916.032087] EXT4-fs error (device sda): ext4_find_extent:909: inode #8: comm jbd2/sda-8: pblk 121667583 bad header/extent: invalid extent entries - magic f30a, entries 8, max 340(340), depth 0(0) [ 1916.073840] jbd2_journal_bmap: journal block not found at offset 4455 on sda-8 [ 1916.081071] Aborting journal on device sda-8. [ 1916.348652] EXT4-fs error (device sda): ext4_journal_check_start:61: Detected aborted journal [ 1916.357222] EXT4-fs (sda): Remounting filesystem read-only This is seen on 4.19-rc, 5.0-rc, mainline, and next. We don't have data for 5.1-rc yet, which is presumably also affected in this RC round. We only see this on x86_64 and i386 devices - though our hardware setups vary so it could be coincidence. I have to run out now, but I'll come back and work on a reproducer and bisection later tonight and tomorrow. Here is an example test run; link goes to the spot in the ltp syscalls test where the disk goes into read-only mode. https://lkft.validation.linaro.org/scheduler/job/735468#L8081 Dan -- Linaro - Kernel Validation
