Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Remember that with internal metadata the last 128MB of the disk are
reserved. I've never used internal much so I can't say for sure, but
this sounds like it could easily be caused by trying to write to that
reserved section of the disk.

Try mke2fs again and explicitly specify the size of the disk as 128MB
smaller than the real size.
