Andrew located at least one bug: we run cancel_dirty_page() too late in
"truncate_complete_page()", which means that do_invalidatepage() ends up
not clearing the page cache.

His patch is appended.

Thanks. I'll try this out later today.

But it sounds like I probably misunderstood something, because I thought
that Martin had acknowledged that this patch actually worked for him.
Which sounded very similar to your setup (he has a 32M ARM box too, no?)

Yup, we have the same machines (Linksys NSLU2) and are running the
same test case (installing Debian). However, I'm not sure what kernel
version he had used for his latest test. I presumed 2.6.20-git,
whereas I had used 2.6.19.

Maybe it's mount option issue? I've got data=ordered on my machine, are
you perhaps runnign with something else?

We are also using ordered.

/dev/scsi/host0/bus0/target0/lun0/part1 /target ext3 rw,data=ordered 0 0
