This is a kernel bug, not an e2fsprogs bug. Can you tell what what version of the kernel you are using?
Inline_data is a feature I generally don't recommend using unless you have a specific reason. It's not on by default. How/when did you enable this feature? And what were you hoping to achieve by enabling it? It looks like you were trying to upgrade some packages when you ran into this issue. Was that something you were doing manually? Are you automatically running "apt-get upgrade" out of cron? Regards, - Ted
