I've tracked down this problem to upstart. With xen-3.0.4, I have a lot of kernel messages like this : "4gb seg fixup, process init (pid 1), cs:ip 73:08051546" "4gb seg fixup, process logd (pid 2429), cs:ip 73:0804b0da"
The only processes generating such warnings are init and logd, both of which come from the upstart package. By recompiling upstart with CFLAGS="-mno-tls-direct-seg-ref" those messages disapeared. I don't know if it is the proper way of fixing this, but it WorksForMe(tm) I attach a debdiff against upstart 0.3.1-1 (from Feisty) The packages are available in my "Xen 3.0.4 for Feisty" repository : deb http://cedric.gabriello.fr/ubuntu feisty xen deb-src http://cedric.gabriello.fr/ubuntu feisty xen ** Attachment added: "upstart debdiff" http://librarian.launchpad.net/6387494/upstart_0.3.1-1sdrik1.debdiff ** Changed in: initramfs-tools (Ubuntu) Sourcepackagename: initramfs-tools => upstart Status: Unconfirmed => Confirmed -- mkinitramfs does not bulid a xen-friendly initrd https://launchpad.net/bugs/77972 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
