I'm using XEN 3.4.2 (Debian unstable packages (3.4.2-2) compiled for lenny) on Debian lenny. I've checked out pv_ops dom0 source as described in the wiki - currently I'm working with changeset 8735edb4a976105fd29c97c00c6d14760537e4ee. domU kernel is a prebuilt kernel image from Debian unstable. The strange thing: With the same binaries, I can't trigger this problem in my test environment (Athlon 64 3500+ socket 939, 2G RAM), only on my production server (2x Opteron 2218 (dual core) socket F, 8GB RAM) - maybe it's a SMP related problem? dom0 .config: http://markus.schuster.name/bugreport/xen/dom0-config.txt kernel output of crashing domU http://markus.schuster.name/bugreport/xen/domU-2.6.31.txt http://markus.schuster.name/bugreport/xen/domU-2.6.32-rc8.txt kernel output of working domU http://markus.schuster.name/bugreport/xen/domU-2.6.29.txt For those just wanting to have a quick look, here is the relevant kernel output from a 2.6.31 domU: [..] [ 0.012368] Booting paravirtualized kernel on Xen [ 0.012368] Xen version: 3.4 (preserve-AD) [ 0.012368] Grant table initialized [ 0.012368] regulator: core version 0.5 [ 0.012368] NET: Registered protocol family 16 [ 0.108050] PCI: Fatal: No config space access function found [ 0.108555] bio: create slab<bio-0> at 0 [ 0.108555] ACPI: Interpreter disabled.
