Package: grub-pc Version: 1.96+20090808-1 Severity: important I have a machine running Xen 3.2 (from the xen-hypervisor-3.2-1-amd64 package). Previously I was using grub-pc 1.96+20080724-16 to boot the hypervisor with a Xen-Dom0-enabled 2.6.26 Linux kernel (from the linux-image-2.6.26-1-xen-amd64 package); this was working fine.
When I upgraded grub-pc and grub-common to 1.96+20090808-1, this broke the booting of the Xen 3.2 hypervisor with an "early fatal page fault" error message like described in the following: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=516610 http://lists.xensource.com/archives/html/xen-users/2009-02/msg00768.html Note that I'm merely referring to the described symptoms. I have no way of telling whether these cases are also caused by a GRUB incompatibility. In my case, however, this is definitely the cause, since downgrading grub-pc and grub-common to 1.96+20080724-16 restores Xen 3.2 to a working state. Note further that I cannot upgrade to Xen 3.4 because, even though it does not hang with an "early fatal page fault" error with the latest GRUB, the Linux kernel then hangs during hardware detection, for possibly unrelated reasons. The currently latest version of GRUB, 1.97~beta2-1, too, makes Xen 3.2 hang with identical symptoms. I see that there were many other GRUB releases between 1.96+20080724-16 (last known good) and 1.96+20090808-1 (first known bad), but I wasn't able to test them. -Julian -- Package-specific info: *********************** BEGIN /proc/mounts /dev/md0 / xfs rw,noatime,attr2,nobarrier,noquota 0 0 *********************** END /proc/mounts *********************** BEGIN /boot/grub/device.map (hd0) /dev/sda (hd1) /dev/sdb (hd2) /dev/sdc (hd3) /dev/sdd *********************** END /boot/grub/device.map *********************** BEGIN /boot/grub/grub.cfg # # DO NOT EDIT THIS FILE # # It is automatically generated by /usr/sbin/update-grub using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### set default=0 set timeout=5 terminal console ### END /etc/grub.d/00_header ### ### BEGIN /etc/grub.d/05_debian_theme ### set menu_color_normal=cyan/blue set menu_color_highlight=white/blue ### END /etc/grub.d/05_debian_theme ### ### BEGIN /etc/grub.d/09_xen ### menuentry "Xen 3.2: Debian GNU/Linux, linux 2.6.26-1-xen-amd64" { multiboot /boot/xen-3.2-1-amd64.gz dom0_mem=512M module /boot/vmlinuz-2.6.26-1-xen-amd64 root=/dev/md0 ro module /boot/initrd.img-2.6.26-1-xen-amd64 } ### END /etc/grub.d/09_xen ### ### BEGIN /etc/grub.d/10_hurd ### ### END /etc/grub.d/10_hurd ### ### BEGIN /etc/grub.d/10_linux ### menuentry "Debian GNU/Linux, linux 2.6.30-1-amd64" { insmod raid set root=(md0) search --fs-uuid --set 2fe9a464-35bf-41b7-9284-5d5932ae06e0 linux /boot/vmlinuz-2.6.30-1-amd64 root=/dev/md0 ro initrd /boot/initrd.img-2.6.30-1-amd64 } menuentry "Debian GNU/Linux, linux 2.6.30-1-amd64 (single-user mode)" { insmod raid set root=(md0) search --fs-uuid --set 2fe9a464-35bf-41b7-9284-5d5932ae06e0 linux /boot/vmlinuz-2.6.30-1-amd64 root=/dev/md0 ro single initrd /boot/initrd.img-2.6.30-1-amd64 } menuentry "Debian GNU/Linux, linux 2.6.26-1-xen-amd64" { insmod raid set root=(md0) search --fs-uuid --set 2fe9a464-35bf-41b7-9284-5d5932ae06e0 linux /boot/vmlinuz-2.6.26-1-xen-amd64 root=/dev/md0 ro initrd /boot/initrd.img-2.6.26-1-xen-amd64 } menuentry "Debian GNU/Linux, linux 2.6.26-1-xen-amd64 (single-user mode)" { insmod raid set root=(md0) search --fs-uuid --set 2fe9a464-35bf-41b7-9284-5d5932ae06e0 linux /boot/vmlinuz-2.6.26-1-xen-amd64 root=/dev/md0 ro single initrd /boot/initrd.img-2.6.26-1-xen-amd64 } menuentry "Debian GNU/Linux, linux 2.6.26-1-amd64" { insmod raid set root=(md0) search --fs-uuid --set 2fe9a464-35bf-41b7-9284-5d5932ae06e0 linux /boot/vmlinuz-2.6.26-1-amd64 root=/dev/md0 ro initrd /boot/initrd.img-2.6.26-1-amd64 } menuentry "Debian GNU/Linux, linux 2.6.26-1-amd64 (single-user mode)" { insmod raid set root=(md0) search --fs-uuid --set 2fe9a464-35bf-41b7-9284-5d5932ae06e0 linux /boot/vmlinuz-2.6.26-1-amd64 root=/dev/md0 ro single initrd /boot/initrd.img-2.6.26-1-amd64 } ### END /etc/grub.d/10_linux ### ### BEGIN /etc/grub.d/30_os-prober ### ### END /etc/grub.d/30_os-prober ### ### BEGIN /etc/grub.d/40_custom ### # This file is an example on how to add custom entries ### END /etc/grub.d/40_custom ### *********************** END /boot/grub/grub.cfg -- System Information: Debian Release: squeeze/sid APT prefers testing APT policy: (600, 'testing'), (90, 'unstable'), (80, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.26-1-xen-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages grub-pc depends on: ii debconf [debconf-2.0] 1.5.27 Debian configuration management sy ii grub-common 1.96+20090808-1 GRand Unified Bootloader, version ii libc6 2.9-25 GNU C Library: Shared libraries ii liblzo2-2 2.03-1 data compression library ii libncurses5 5.7+20090803-1 shared libraries for terminal hand grub-pc recommends no packages.
