This problem was fixed by dodgy NCQ on the disk itself, S/N: WMANM2828677 P/N: WD1600JS-60MHB1 (Western Digital 160Gb). If I disabled the disk it worked fine, or replaced the disks with Some Seagates it worked fine also! I am running a 2.6.19 at the moment quite happily. Still want me to test a 2.6.20.1? I might be able to get a bit of time later on this week. -- James Ray. Computing Services Queen Mary, University of London
