I am also having a shitload of problems on my newly installed 5.3 box (which 
was a happy camper under 4.x. I have a promise tx2 100 board. there are a 
pair of disks with a geom stripe over them,  Under heavy i/o the system 
either freezes or crashes. I will have some time later next week to 
investigate but I am really inclined to use the time to revert to 4.11.
