No, a second machine of the same type is available now for testing - and also crashing after
loading of the cassini driver. Here lspci and cpuinfo:

This machine has 24G RAM, 16 on one board and 8 on the other. The first machine has one board with 16G.
So it may be a memory issue, as Aron has only 14G. Other maybe the OBP version - here is the latest installed
on all machines. Just to rule out a firmware issue:

$ md5sum /lib/firmware/sun/cassini.bin

Any further ideas to debug deeper ?
