I've built world, kernel etc and installed it using GENERIC kernel done my mergemaster, delete old, delete old-libs and I still have the problem. I'm wondering if it's due to the single 6 Gb drive in my raidz2 (the other 7 are 3 Gb). I've heard that the new driver doesn't like mixed speeds in a raid set when using -IR firmware but I wouldn't expect an issue with ZFS with -IT firmware. It seems that there may be a general incompatibility with both the old and new drivers and the Western Digital WD20EARX-00P 6 Gbps drive. Unfortunately I cannot get the old 3 Gb drive anymore. I'll try moving the WD20EARX-00P drive to the on board SATA ports next.
