I have a RAID 5 (3 drives) on LSI MegaRAID SATA 150-4
On it there is a pool that needs rebuilding

Sys is on separate IDE drive

Each time I run anything I/O intensive (like nss/poolrebuild) after ~ 9% I
get the above message & server crashes

There is NOTHING else loaded as server is started with -na -nl switches

Anybody any idea how to get thei drivers to remain?
There is nothing wrong with the physical card, as I have tested 2 so far &
they both work perfectly under W2K3 server
