Public bug reported: Binary package hint: mountall
Ubuntu 9.10, which introduces the mountall utility, is unable to boot under a Debian 2.6.26 Xen domU kernel. When the boot process is edited to show us what mountall is doing, it becomes stuck on "mounting /sys/kernel/debug". Here is the full boot log: track_usplash: will not start usplash parse_filesystems: reading filesystems parse_filesystems: sysfs (nodev) parse_filesystems: rootfs (nodev) parse_filesystems: bdev (nodev) parse_filesystems: proc (nodev) parse_filesystems: cgroup (nodev) parse_filesystems: cpuset (nodev) parse_filesystems: debugfs (nodev) parse_filesystems: securityfs (nodev) parse_filesystems: sockfs (nodev) parse_filesystems: usbfs (nodev) parse_filesystems: pipefs (nodev) parse_filesystems: anon_inodefs (nodev) parse_filesystems: tmpfs (nodev) parse_filesystems: inotifyfs (nodev) parse_filesystems: devpts (nodev) parse_filesystems: ramfs (nodev) parse_filesystems: mqueue (nodev) parse_filesystems: ext3 new_mount: /: /dev/root rootfs defaults check new_mount: /proc: - proc nodev,noexec,nosuid new_mount: /proc/sys/fs/binfmt_misc: - binfmt_misc nodev,noexec,nosuid,optional new_mount: /sys: - sysfs nodev,noexec,nosuid new_mount: /sys/fs/fuse/connections: - fusectl optional new_mount: /sys/kernel/debug: - debugfs optional new_mount: /sys/kernel/security: - securityfs optional new_mount: /spu: - spufs gid=spu,optional new_mount: /dev: - tmpfs mode=0755 hook new_mount: /dev/pts: - devpts noexec,nosuid,gid=tty,mode=0620 new_mount: /dev/shm: - tmpfs nosuid,nodev new_mount: /tmp: - - - hook new_mount: /var/run: - tmpfs mode=0755,nosuid,showthrough hook new_mount: /var/lock: - tmpfs nodev,noexec,nosuid,showthrough new_mount: /lib/init/rw: - tmpfs mode=0755,nosuid,optional parse_fstab: updating mounts update_mount: /proc: proc proc defaults new_mount: none: /dev/sda1 swap sw update_mount: /: /dev/sda2 ext3 noatime,nodiratime,errors=remount-ro,relatime check parse_mountinfo_file: updating mounts update_mount: /sys: - sysfs nodev,noexec,nosuid update_mount: /proc: proc proc defaults update_mount: /dev: udev tmpfs mode=0755 hook update_mount: /: /dev/sda2 ext3 noatime,nodiratime,errors=remount-ro,relatime check new_mount: /dev/.static/dev: /dev/sda2 ext3 - mount_policy: /proc/sys/fs/binfmt_misc: dropping unknown filesystem mount_policy: /sys/fs/fuse/connections: dropping unknown filesystem mount_policy: /spu: dropping unknown filesystem mount_policy: / is local (root) mount_policy: /proc can be mounted while root readonly mount_policy: /proc prior fstab entry / mount_policy: /proc is virtual mount_policy: /sys can be mounted while root readonly mount_policy: /sys is virtual mount_policy: /sys/kernel/debug parent is /sys mount_policy: /sys/kernel/debug is virtual mount_policy: /sys/kernel/security parent is /sys mount_policy: /sys/kernel/security is virtual mount_policy: /dev can be mounted while root readonly mount_policy: /dev is virtual mount_policy: /dev/pts parent is /dev mount_policy: /dev/pts is virtual mount_policy: /dev/shm parent is /dev mount_policy: /dev/shm is virtual mount_policy: /tmp parent is / mount_policy: /tmp is local mount_policy: /var/run can be mounted while root readonly mount_policy: /var/run is virtual mount_policy: /var/lock can be mounted while root readonly mount_policy: /var/lock is virtual mount_policy: /lib/init/rw can be mounted while root readonly mount_policy: /lib/init/rw is virtual mount_policy: /dev/sda1 is swap mount_policy: /dev/.static/dev parent is /dev mount_policy: /dev/.static/dev is other (default) mounted: /proc mounted: local 0/2 remote 0/0 virtual 1/10 swap 0/1 mounted: /sys mounted: local 0/2 remote 0/0 virtual 2/10 swap 0/1 mounted: /dev dev_hook: populating /dev mounted: local 0/2 remote 0/0 virtual 3/10 swap 0/1 mounted: /dev/.static/dev mounted: local 0/2 remote 0/0 virtual 3/10 swap 0/1 try_mount: / waiting for device /dev/sda2 queue_fsck: /sys/kernel/debug: no check required mounting /sys/kernel/debug Please fix this as soon as possible before more people who run Ubuntu Server on Xen virtual machines shoot themselves in the foot.
