The messages show up during the initial dom0 boot, before any domUs are loaded. I've attached a second xl dmesg log which is similar to the first, but the numbers in the error messages are different. The messages are hardware dependant as I don't get them on another system with different hardware configuration but with identical software. The motherboard is a ASUS M2N68 AM PLUS, with 4GB of RAM. If I remove one of the sticks of ram to take it down to 2GB, the mm.c errors are no longer displayed, but I still get the traps.c message. --------------050007020003000209050007 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit

Do they show up during bootup? As in do you see those _when_ you launch your guests?
To figure out this particular issue you should try using 'console_to_ring' (so that
dom0 output and Xen output are mingled togehter) and also post this under a new subject
to not confuse this email thread.

The messages show up during the initial dom0 boot, before any domUs are loaded. I've attached a second xl dmesg log which is similar to the first, but the numbers in the error messages are different.

The messages are hardware dependant as I don't get them on another system with different hardware configuration but with identical software.
