[ PLease keep me in Cc:, I'm not subscribed to this list ] Hi, I'm working on getting domain0 support in NetBSD (i386 for now) for Xen-3. I have a bootable kernel which is working fine under xen-3.0.0, with hardware device support and limited support for xentools. Now I tried to switch to 3.0.2-2, and the serial console hangs shortly after my domain0 kernel enables interrupts. If I call the NetBSD kernel debugger just after enabling interrupts I can type a few chars before in hangs. With ^A^A^A I can switch the input to Xen, and the message "switching input ..." is printed. However from here, only R is functionnal (it prints the message and reboot), all others commands produce no outputs, including 'h' (this is a xen kernel rebuilt with debug options). The same xen kernel works fine with a linux dom0, including the debug actions (I tested h, q, i at last) so it's probably not a compile option issue. Maybe it's an interrupt issue, but I'm not sure as ^A and R are still working fine. I noticed there were changes in the include/public interfaces between 3.0.0 and 3.0.2, including a new hypercall to unmask event. I've not updated my NetBSD domain0 to this yet. Could this be the cause ? Any other idea on what could cause this ? -- Manuel Bouyer <bouyer@xxxxxxxxxxxxxxx> NetBSD: 26 ans d'experience feront toujours la difference -- _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
