[Xen-users] shutdown of pci-paththrough-domU freezes dom0
Hi there, I faces an issue I try to solve a couple of days. When I start a domain without pci-passthrough I can shutdown, destroy it without problems. If I pass a pci-device through the domain (e.g. dvb-cards) it freezes the hole system when it shut down. On the local terminal I see a load-increase through the roof. The gnome-systemmon-tray refreshs, the rest of the system doesn´t respond. A htop in a local terminal freezes like the rest of the desktop, network, etc.. I run 3.4.2 with an 2.6.31.6-kernel from jeremy: git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git My guess would be it depends on the pci-passthrough and IRQ-release... :) But I`m kind of stuck here. Maybe anyone face this issue too and could give a hint. Thanks and a happy new year to everyone.. Christian -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT!

Might be worth trying linux-2.6.18-xen in dom0, and see if that works better. That would at least tell you if the bug is in Xen or in dom0 kernel. http://wiki.xensource.com/xenwiki/XenDom0Kernels -- Pasi _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
