Okay, if you want to check out the 'fix' to revert behaviour to that of 3.0.4 for yourselves, it is to edit linux/include/asm-i386/mach-xen/asm/pci.h and to change the definition therein of pcibios_scan_all_fns() from 0 to 1. If you are building a 64-bit kernel then of course it is the file in include/asm-x86_64 that you need to edit. Make that change and rebuild you domU. Additionally, make sure you build dom0 with pciback in passthrough mode. Hopefully your problems will be gone! Let me know how you get on -- if successful I may check this change back into our linux-2.6.18-xen.hg repository. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
