I'm saying that it works fine - no panic - with the feature disabled: -E lazy_itable_init=0. (I'm sorry about that. I was filing just a little too quickly after informing Ted via IRC. It's been a long hunt.) Again, it panics easily with lazy_itable_init set to its default, which means without using the switch. In addition to what I initially reported, I've made more than 80 additional ffsb runs on freshly made ext4, ext4 nojournal, and ext4 mblk_io_submit filesystems over the last three days with lazy_itable_init=0, and there have been no further panics. For the record, I'm using e2fsprogs 1.41.14 straight from Ted's git tree.
