Kernel boot logs
I'm guessing this is a result of our kernel-xen still being based on the 3.0.4 patches. There was this changeset in 3.1.0 tree which I'm sure would be a pre-requisite for 32-on-64 to work: changeset: 13573:c9ac0bace498 user: kfraser date: Wed Jan 24 10:38:17 2007 +0000 files: linux-2.6-xen-sparse/drivers/xen/blkback/blkback.c linux-2.6-xen-sparse/drivers/xen/blkback/common.h linux-2.6-xen-sparse/drivers/xen/blkback/interface.c linux-2.6-xen-sparse/drivers/xen/blkback/xenbus.c linux-2. 6-xen-sparse/drivers/xen/blktap/blktap.c linux-2.6-xen-sparse/drivers/xen/blktap/common.h linux-2.6-xen-sparse/drivers/xen/blktap/interface.c linux-2.6-xen-sparse/drivers/xen/blktap/xenbus.c linux-2.6-xen-sparse/include/xen/b lkif.h xen/include/public/io/blkif.h description: bimodal blkback: Support multiple ring protocols. This is needed for 32-on-64 support. Right now there are three protocols: native, x86_32 and x86_64. If needed it can be extended. Interface changes (io/blkif.h) * Define the x86_32 and x86_64 structs additionally to the native version. * Add helper functions to convert them requests to native. Backend changes: * Look at the "protocol" name of the frontend and switch ring handling accordingly. If the protocol node isn't present it assumes native protocol. * As the request struct is copied anyway before being processed (for security reasons) it is converted to native at that point so most backend code doesn't need to know what the frontend speaks. * In case of blktap this is completely transparent to userspace, the kernel/userspace ring is always native no matter what the frontend speaks. Signed-off-by: Gerd Hoffmann <kraxel> There's a couple of other changesets too, so I think we should wait until kernel-xen is updated to 3.0.5 before investigating this further. change QA contact Based on the date this bug was created, it appears to have been reported against rawhide during the development of a Fedora release that is no longer maintained. In order to refocus our efforts as a project we are flagging all of the open bugs for releases which are no longer maintained. If this bug remains in NEEDINFO thirty (30) days from now, we will automatically close it. If you can reproduce this bug in a maintained Fedora version (7, 8, or rawhide), please change this bug to the respective version and change the status to ASSIGNED. (If you're unable to change the bug's version or status, add a comment to the bug and someone will change it for you.) Thanks for your help, and we apologize again that we haven't handled these issues to this point. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again. This is addressed in F8. |
