Presumably one of your filesystems is using htree (indexed directories). It's a bug - nobody has found it yet.
The modestly good news is that I have found a workload which triggers it in ten minutes, but I have not looked into it at all.
The modestly bad news is that e2fsprogs-1.32's mke2fs enables htree by default. It really shouldn't be doing that - htree isn't ready yet.
Use
dumpe2fs -h /dev/hda1 | grep dir_index
to see if htree is enabled.
Use
tune2fs -O '^dir_index' /dev/hda1
to disable it.
There are no trmendously bad bugs in htree. Mainly this one (which _could_ cause crashes and scribbled directories) and a small memory leak on each unlink.
