** Summary changed: - "-generic" kernel doesn't boot in Gutsy on some occasions, freezes at the splash screen and then drops to initramfs prompt + Failure to mount root filesystem, cause unknown
** Description changed: - My system profile is here, according to a tool on my computer: - http://hwdb.ubuntu.com/?xml=1f04acee99d97fae095286849a50f8c0 + This report and its comments describe symptoms of a problem wherein the + root filesystem is not mounted after a kernel upgrade. - I just upgraded my dapper workstation to the Edgy prerelease, which - installed both linux-image-2.6.17-10-386 and linux- - image-2.6.17-10-generic. The 386 one boots fine but doesn't enable SMP, - so I tried selecting the -generic kernel from the GRUB menu. - - The regular -generic option causes my screen to blank and display only a - blinking cursor; there are no Linux kernel bootup messages (and of - course no expected splash screen). I didn't wait for very long (say, two - minutes), but I saw no hard drive activity according to the LEDs. - - Selecting the recovery version of the -generic kernel started what - seemed to be a normal recovery bootup process, until it got to this - part: - - Begin: Mounting root file system... ... - Begin: Running /scripts/local-top ... - [[timestamp]] hda: PLEXTOR DVDR PX-716A [...] - [[timestamp]] ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 - cat: /etc/mdadm/mdadm.conf: No such file or directory. - Done. - Begin: Waiting for the root file system... ... - - At this point, something between two and five minutes passed. Then more - output followed: - - Done. - ALERT! /dev/disk/by-uuid/ad313939-c7a7-447c-8591-79210c820840 does not exist. Dropping to a shell! - - BusyBox v1.1.3 (Debian 1:1.1.3-2ubuntu3) Built-in shell (ash) - - /bin/sh: can't access tty; job control turned off - (initramfs) - - Typing "ls /dev/disk" then said - - ls: /dev/disk: No such file or directory. - - - "ls /dev" does show a bunch of stuff, so at least that directory exists. - - I can live with the -386 kernel for now, but it is bewildering that it - would work and -generic wouldn't. + It is unlikely that they share a common cause, and further analysis is + needed to isolate the problem(s). -- Failure to mount root filesystem, cause unknown https://bugs.launchpad.net/bugs/67256 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
