Every time an md device finished resyncing, I would get this on the console, although things did keep working: ov 4 14:21:21 tornado kernel: md: md10: sync done. Nov 4 14:21:21 tornado kernel: md: syncing RAID array md6 Nov 4 14:21:21 tornado kernel: md: minimum _guaranteed_ reconstruction speed: 1 000 KB/sec/disc.

I noticed a heap of patches out today from NeilB, are these likely to solve this problem? Reuben
