I had thought the dumps were being corrupted but taking another look I've found the machine started generating core.txt files a couple of days ago which confirmed the crashes happening in fpu_kern_leave. I've built a kernel with the kern_fpu.3.patch and the machine has survived lots of network and disk traffic, which would normally have caused a crash. -- Bruce Cran
