Hi Alex,

I tried git bisect and it ended up in a qla2xxx fix (and I do not even
have qlogic card in that system).

I did it couple more times and landed on different patches.

My latest (fourth ot fifth, I forgot :) bisect landed on the patch with
commit 546a1924224078c6f582e68f890b05b387b42653 ( writeback:
write_cache_pages doesn't terminate at nr_to_write <= 0)

I verified that this is valid patch by running the test script 180 for
nearly 500 times on the tree just prior to this patch.
