Hi,
i described it a little more in detail in
http://lkml.org/lkml/2007/9/25/184 2 months ago.
The kernel oopses often when there is (heavy) disk access, but not
always, thats the point, sometimes it runs 4 weeks, sometimes only a
few days. With older kernels sometimes the software raid was out of sync
and one disk was gone, with ne "new" kernel nothing like this happend.
