You can use man crash command. I use command sudo crash vmlinux to analyze a live system.

Not sure why your writes should be blocking, they should return as soon as they
write data to page-cache.I haven't checked, but I assume that my backed up writes have filled the page cache (it is a pretty memory constrained embedded Linux system).

Can you run crash on this live system and see where this write call/process is blocked?
I can try, but I don't know this tool. And "crash" was not most search friendly term. ;) Do you mind helping out with a URL?
