Hello, I have been running NetBSD/i386 and Xen on a Supermicro server with an Areca RAID controller for about 1.5 years now and everything is working well.
I would like to replace the NetBSD i386 dom0 with amd64 port to be able to access 8 GB of RAM. However, amd64+xen does not work well with the Areca controller - most of NetBSD builds make the system panic at a random point. If I run the system from a SATA drive connected to the motherboard's SATA port, everything works just fine (with the same Xen and NetBSD binaries). The amd64 port itself works just fine with Areca, too - it's only the amd64+xen+areca combination that is causing problems. And with the i386 port, xen and Areca work ok. I'm using Xen 3.3.1 and a netbsd-5 amd64 dom0 kernel built a week ago. I don't have a backtrace available, I need to hook up a display and a keyboard first (the remote console does not work with kernel debugger). I'd appreciate it if someone more knowledgeable could help debugging this - the other option is to install linux as dom0, but I'd rather use the NetBSD amd64 port as I have never maintained a linux system before. Thanks, -jm
