This is a debian bugreport but thought I'd post it here to expose it to the right audience.. Screenshot-photos of the panic can be found at http://www.osp.fi/xen1.jpg , http://www.osp.fi/xen2.jpg and http://www.osp.fi/xen3.jpg //Markus Package: linux-image-2.6.17-2-xen-k7 Version: 2.6.17-9 Severity: critical Justification: breaks the whole system Xen 3.0 unstable in debian etch crashes horribly and reboots the system when booting virtual domains with linux-image-2.6.17-2-xen-k7 kernel. Took a photo of the panic message and lost some values in the process. Below is what could be salvaged: esi: 00000000 edi: 05555000 ebp: 00000104 esp: b0379e0c ds: 007b es: 007b ss: 0069 Process xenwatch (pid: 7, threadinfo=b0378000 task=b0daba90) Stack: <0>93e42f51 b0379eac b1c4e080 00000000 b0daba90 b0dab580 b1c4e940 b0da???? 0 b037bf58 b0278c25 b0379e94 0000000a b0a61740 00000000 0000000??? 00000104 b013444a b0379eac 00004100 b02fd380 00000104 b0a6 1740 b013450???
