This is presumably because the machine is full of memory which
is dirty against a slooow device.
You can work around this by reducing the dirty memory thresholds:
akpm-1:/home/akpm> cat /proc/sys/vm/bdflush
30 64 64 256 30000 3000 60 0 0
Make the "30" and "60" smaller. 10 and 20 perhaps.
Better: change the application to fsync() the data every few
megabytes, or open O_SYNC.
