That solved my issue. Just disabling interrupts before i call my idle function did the trick. Mathieu

Announcing OpenBSD/amd64 Xen port
Hi, I've been working toward porting OpenBSD/amd64 for the Xen Virtual Machine Monitor for a few months. It's not 100% complete, but most is already working for domU. Here's a list of the current issues/missing things: - virtual NIC driver is not fonctionnal, some part of the code still needs to be fixed for packet transfer from/to Xen to work. - events/clock issue: there seems to be a race condition leading to clock not ticking, hence putting system to sleep till a keyboard/network/disk interrupt is received. - SMP is currently not supported. I'll make a kernel binary, a disk image and sources available shortly. Regards, Mathieu
