Applied try 3 of Nick Piggin's patch to 2.6.30-rc3 (cleanly, no less!)
Doesn't appear to have helped at all - I received my favorite BUG ON
write.c:252 just like always, within 24 hours of booting the kernel,
even.

Yes. I'm able to reproduce this bug now. I found that I can trigger it
fairly reliably by running iozone in something like the following
configuration: "iozone -t 32 -r 1k -s 256m -c -D -K -Z -i0 -i8"
I believe it boils down to the problems being discussed in the following
thread:
