Hi Andre and Murray (++), > Come on, a little more detail on the hardware would have been nice.
I didn't want to jump straight into solution mode, but since you've asked: Gigabyte GA-MA770-US3 motherboard (v1.0) AMD Phenom II 920 (2.8GHz, 6MB cache) 8GB (DDR2-800MHz 2GB * 4 memory, non ECC) BIOS version F4 (updated from the default F3 version). 2 * Seagate ST75000333 SATA2 (32MB cache) No other OSes on the system (phew). One zpool with a RAID1 setup BIOS set to AHCI mode NVidia Graphics card (8600 series) Yes, I have tried "other" OSes (Windows "Me too 7", Ubuntu 9.04) on other disks. (**) OpenSolaris has panicked the most - but I'm not being critical of it - perhaps the other OSes just can't drive the hardware to the limit. > perhaps writing > very large files and then checking the md5 to make sure they're not > corrupted? > when unpacking archives, because they're checksummed - and the problem was > memory timings, mostly.

I haven't seen any errors in "iostat -E", and ZFS would surely pick up any mis-read blocks. (zpool status shows zero checksum errors). (**) For what it's worth Windows 7 can't even format AHCI disks. -- Regards, Chris
