Hi,
I wasted some time looking into this. If the file is in cache, it
seems to work ~ok. I can reproduce a lock simply by doing losetup
/dev/loop0 ext2image; fsck -f /dev/loop0 after fresh boot.
The kdb trace.. (screen of box about to do XXXth 20gig fsck:)

___wait_on_page+0x183

lo_receive+0x57

system_call
Nothing I tried resulted in anything other than fsck runtime.
