Ditto. On a VERY loaded system (so loaded that it crash every now and
then because of the load). Haven't had ANY trouble what so ever with
RAID6. I'm very (!) happy with it!
This on 4x9Gb + 2 spares. Use it on the system/root filesystem only
though... Which isn't THAT loaded now when I think about it...
If I could, i'd convert all my RAID5 sets to RAID6. But I don't have
time for the downtime. I'll monitor this subject closely though... :)

Mine is a 2.6.12.4 on a Sun Blade 1000 (2x750MHz UltraSPARC III) CPU's
(now) with 2Gb mem...

Same here. I've been fortunate to not have a disk crash so I can't
say how stable/good RAID6 is if disks start krashing :)
