[Bug 1475941] Re: Kernel panic - not syncing
I am attaching a screen shot of my problem because it looks so similar and I haven't had any luck in solving it. I can still boot with the Linux 3.19.0-21-generic kernel from the Grub menu. However the more recent versions (22 through 25) are not booting. I am not sure how to tell for certain but it looks more and more like the same kind of problem. ** Attachment added: "IMG_20150807_145055965_HDR.jpg" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1475941/+attachment/4441216/+files/IMG_20150807_145055965_HDR.jpg -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1475941 Title: Kernel panic - not syncing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1475941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1475941] Re: Kernel panic - not syncing
I've installed kernel 3.19.0-25, and now it's not enough to remove the quiet option even in 3.19.0-22. I have to manually edit the grub menu entry at boot time (writing it on grub.cfg doesn't work) and replace the following lines: if [ x$feature_platform_search_hint = xy ]; then search --no-floppy --fs-uuid --set=root --hint-bios=hd0,msdos7 --hint-efi=hd0,msdos7 --hint-baremetal=ahci0,msdos7 0e051a2e-be67-40a6-8d32-29d4de69aca1 else search --no-floppy --fs-uuid --set=root 0e051a2e-be67-40a6-8d32-29d4de69aca1 fi with this: search --no-floppy --fs-uuid --set=root --hint- bios=hd0,msdos7 --hint-efi=hd0,msdos7 --hint-baremetal=ahci0,msdos7 0e051a2e-be67-40a6-8d32-29d4de69aca1 That is true also for the newest kernel – if I don't do that, I get the kernel panic message I described before. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1475941 Title: Kernel panic - not syncing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1475941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Not at all. This is a clean install so the earliest kernel version is 3.19.0-15 which has this bug. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1475941 Title: Kernel panic - not syncing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1475941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1475941] Re: Kernel panic - not syncing (clean 15.10 install)
Fibonacci, are you able to boot into a prior kernel version via GRUB that doesn't demonstrate this problem? ** Tags added: latest-bios-0160 ** Summary changed: - Kernel panic - not syncing (clean 15.10 install) + Kernel panic - not syncing ** Description changed: - I've just installed Kubuntu 15.10 and was able to boot into it once and + I've just installed Kubuntu 15.04 and was able to boot into it once and update the kernel. Since then, everytime I try to boot into it I get the following error message: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown- block(0,0) There might be other error messages before but I cannot see them as they pass too fast, and the only messages I see are those shown in the attached picture. After some trial and error, I've discovered that this bug occurs when booting with the quiet option. When I remove it, the kernel boots fine most of the time (not everytime, but it's a definite improvement). What's happening and how do I prevent it?

[Bug 1475941] Re: Kernel panic - not syncing (clean 15.10 install)
I have a 64-bit System76 computer and this problem also affects me. My kernel is 3.19.0-22-generic. I am using factory-installed Ubuntu 15.04, but I've been running updates regularly. I can still boot my original 3.19.0-21-generic kernel just fine, and do my work on that kernel without any problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1475941 Title: Kernel panic - not syncing (clean 15.10 install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1475941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The 15.10 kernel has been rebased to v4.0. Can you get the system to boot, then apply the latest updates and see if this bug still exists? ** Changed in: linux (Ubuntu) Importance: Undecided => High ** Tags added: kernel-da-key -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1475941 Title: Kernel panic - not syncing (clean 15.10 install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1475941/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
