Public bug reported: I have done yesterday the update (with the Gnome update manager) from ubuntu 8.10 to 9.04, and now I can no longer boot my computer. The update seems to have worked properly but gaved a lot of small errors (to which I did not pay attention at the time), including missing modules in X server and the fact that it was unable to connect to some configuration server. But these things are not related I think to a early boot problem.
At the grub prompt I only have two different kernels : 2.6.28-11-generic and 2.6.27-11-generic. And the same happen for both of them. After some seconds of boot I get the following message : ------------------------- Gave up waiting for root device. Common problem: - Boot arg (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough ?) - Check root= (did the system wait for the right device?) - Missing modules (cat /proc/modules; ls /dev) ALERT! /dev/md0 does not exists. Dropping to a shell! ------------------------- >From there, if I enter "exit" I get the same message again, even if I wait for a long time (several minutes) or if I use rootdelay=90 in the boot command line (as suggested here http://www.ubuntu.com/getubuntu/releasenotes/904#Boot%20failures%20on%20systems%20with%20Intel%20D945%20motherboards ). In the busybox shell I can enter the following commands (I copy manually the output as I can't do anything else on this faulty computer) : -------- cat /proc/modules r8169 mii floppy raid10 raid456 async_xor async_memcpy async_tx raid1 raid0 multipath linear vesafb fbcon tileblit font bitblit softcursors -------------------------- ------------- uname -a Linux (none) 2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:58:03 UTC 2009 x86_64 unknown -------------------------- If a look into /dev, I can see all of my hard drive and partition except for /dev/md0 which is the root device. Booting with 2.6.27-11-generic yields the same result but after a longer boot, during which I can see that all my hard drive are also properly recognised. My hardware is an ASUS P5B motherboard with an Intel P965 chipset, SATA hard drives on an Intel ICH8 controller and UDMA optical drives on a JMicron JMB363 PATA controller. My root device is /dev/md0 which is a software raid1 array (with two devices /dev/sda2 and /dev/sdb2). This may be the same than bug #335619 whick lacks a lot of information, but I think that it is not bug #290153 (or any other bug corrected by waiting at the busybox shell before proceeding with the boot) as adding rootdelay=90 (or a greater value) does not solve my problem. It is neither bug #33269 as the error is different. Tell me if I can give more information, but I can't boot that computer so every thing will have to be copied by hand. ** Affects: ubuntu Importance: Undecided Status: New -- boot failure with raid1 array on jaunty https://bugs.launchpad.net/bugs/367934 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
