I noticed a somewhat significant difference between patch #0002 and a busy wait loop with ndelay(10). Write performance was equivalent in both cases as should be the case. Read perfomance for me maxed out around 150ish megabit whereas switching to the ndelay(10) loop brought up average performance around 350ish megabit while reading the same files over samba. --David Madsen
