See http://www.infradead.org/rpr.html Hi all, I've just been wanting to test my changes to the inline encruption fallback code, and it seems like ext/004 (the only ext4 dump test) hangs when using the following options: export MKFS_OPTIONS='-O encrypt' export MOUNT_OPTIONS="-o inlinecrypt,test_dummy_encryption" I thought I did not see this before, but it reproduces back to at least Linux 6.17. This is in an uptodate Debian trixie VM. The dump/restore process look like in weird states: 4727 ttyS0 T 0:00 /usr/sbin/dump -0 -f - /mnt/scratch/dump_restore_dir 4728 ttyS0 T 0:00 /usr/sbin/restore -urvf - 4729 ttyS0 T 0:00 /usr/sbin/dump -0 -f - /mnt/scratch/dump_restore_dir 4730 ttyS0 T 0:00 /usr/sbin/dump -0 -f - /mnt/scratch/dump_restore_dir 4731 ttyS0 T 0:00 /usr/sbin/dump -0 -f - /mnt/scratch/dump_restore_dir 4732 ttyS0 T 0:00 /usr/sbin/dump -0 -f - /mnt/scratch/dump_restore_dir
