Just so everyone knows this problem still bites - I spent the last 2 weeks struggling
with failures in a Raid 5 system that had been flawless for years. After a hard drive replacement
we used 8.9.xxxx for rebuilds and the fireworks began. Usually the rebuild would complete
but within hours of use a drive would fail (apparently during paging operations of some kind).
After trying everything we could imagine we found this thread with the downgrade recommendation.
With 8.8 after one rebuild, there we have once again found smooth sailing.
(I purposely left out details of Drive replacements, tests and so-called expert efforts, all the other
posts give plenty of detail)
Why did we not just move all the way up to the current new versions instead
of choosing 8.9 at this late date? Because the machine in peril was an important
windows server 2003 machine and the newer Intel drivers do not list 2003 as supported...
(someday we will move all to 64-bit systems in one shot - maybe later this year)
Anyway - this thread still is magic - and Intel should have probably pulled the 8.9 years ago.
8.8 Solved our issues immediately.
