Hmm how did I miss that... fixed now, thanks.

diskstat.sh hde

My output looks like this:

This is during a sequential write, only one writer. File received via
network.

Everything's humming along fine at 11-12MB/s until row 249, there it
drops to 2-4MB/s and the machine freezes for 1-2 seconds every 3-10
seconds. Data taken from /proc/diskstats and is in the same order as
those fields (documented in Documentation/iostats.txt).

Don't know if it's related to your problems in any way.
