I am still having these problems -
2 RAID5s with 3 drives each (10 MB per drive for fast rebuild) i get
an instant "Got MD request, not good" kernel hang when doing an mke2fs on
the stripe containing the both raid5s ... Very bad - This should
work from the manpages but doesn (Reproducable with large and small
stripe/raid sets)
BTW: I am UP 2.2.12plain + raid patches ...
BTW: The Hang does occur within rebuild and afterwards - Doesnt matter ..
