Re: [Xen-users] Yes, it does! (Does the amount of main memory influence
Hi Stephan,
I'm pretty sure,
I was building a cluster, of two identical systems with motherboard
DQ45CB. the behavious was the same on both.
In each I had 2 modules of 2 gig. and both modules worked when inserted
in the system.
Until this day the dmesg show some error but the system is working fine
in production, (Uptime of 60 days + passthrough and still counting). I
posted the dmesg before but no reaction then. Again with this output
the system is working and I'm not sure If it is related. De dmesg of
the freezing system I was never able to capture.
==== xm dmesg begin======

I seen the same problem with motherboard

is working fine, including the pci pass-through.
Are you sure that you don't have defective memory? In my case
everything but PCI Pass Through runs fine with any memory size (no
freezes).
