[Bug 974765] Re: Drive not found since 3.2.0-21... kernel panic, unable to mount root fs
I have performed some more work towards this issue and I have found that it is an issue not with the kernel but with the generation of initrd.img. Ubuntu-3.2.0-20-generic is the kernel I received upon initial install via CD-ROM. This kernel came with the proper initrd.img-3.2.0-20-generic image. update-grub detects both kernel and ramdisk image correctly, and the system boots fine. Ubuntu-3.2.0-21-generic and Ubuntu-3.2.0-22-generic will installed via repository (normal system update). initrd.img does not exist for either of these kernels. Consequently, update-grub does not generate initrd lines for these kernels and they fail to mount the system partition due to lack of necessary modules. I built Ubuntu-3.2.0-23 from the Ubuntu kernel git repository via: $ fakeroot debian/rules clean $ fakeroot debian/rules binary-headers binary-generic and installed the resulting debs: * linux-headers-3.2.0-23_3.2.0-23.36_all.deb * linux-headers-3.2.0-23-generic_3.2.0-23.36_amd64.deb * linux-image-3.2.0-23-generic_3.2.0-23.36_amd64.deb Again, initrd.img-3.2.0-23-generic was never generated for some reason. So, naturally, booting this also failed. I was able to get Ubuntu-3.2.0-23-generic to boot by: 1) making a copy of my working initrd.img-3.2.0-20-generic 2) unpacking it 3) rename lib/modules/3.2.0-20-generic to lib/modules/3.2.0-23-generic 4) repacking 5) moving to /boot/initrd.img-3.2.0-23-generic I know this is a terrible hack, but I am not sure how to generate a proper initrd.img by hand. In short, initrd.img is not being generated after kernel installation by initramfs-tools on my system for some reason. I am not familiar enough with the generation of initrd.img to know where the failure could be. Help is, of course, appreciated in tracking the source of the error. Regardless, this is no longer really a kernel bug and should probably be reassigned or closed/re-opened as appropriate. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974765 Title: Drive not found since 3.2.0-21... kernel panic, unable to mount root fs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/974765/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 974765] Re: Drive not found since 3.2.0-21... kernel panic, unable to mount root fs
Yes, I can confirm that on my system the problem is with update- initramfs. After kernel installation, update-initramfs is invoked via /etc/kernel/postinst.d/initramfs-tools. However, initrd.img is not created. In fact, update-initramfs seems to do nothing. Running update-initramfs manually via: $ sudo update-initramfs -c -t -k 3.2.0-21-generic -v Produces no output. Running: $ update-initramfs also produces no output. Not even the usage as in 10.04 LTS. However, I am able to use /usr/sbin/update-initramfs from my working 10.04 LTS partition to generate the initrd.img images. So, it looks like a problem with update-initramfs I tried: $ sudo apt-get clean $ sudo apt-get autoclean $ sudo apt-get --reinstall install initramfs-tools but this did not seem to change anything. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974765 Title: Drive not found since 3.2.0-21... kernel panic, unable to mount root fs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/974765/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I am removing the 'needs-bisect' tag. It should be noted that in Post #10 I only mentioned building 3.2.0-23, but I also built 3.2.0-9, 3.2.0-20, 3.2.0-21, and 3.2.0-22. All of these build failed to boot due to lack of initrd.img. Naturally, the bisection failed because I could not find a good version since the problem was related to update-initranfs and initrd.img generation... not the kernel.

Hi Christopher. No problem. However, I am currently traveling so I will not be able to perform the kernel bisection until I return on Tuesday. I apologize for this delay. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974765 Title: Drive not found since 3.2.0-21... kernel panic, unable to mount root fs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/974765/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Thank you for taking the time to file a bug report on this issue. However, given the number of bugs that the Kernel Team receives during any development cycle it is impossible for us to review them all. Therefore, we occasionally resort to using automated bots to request further testing. This is such a request. We have noted that there is a newer version of the development kernel than the one you last tested when this issue was found. Please test again with the newer kernel and indicate in the bug if this issue still exists or not. You can update to the latest development kernel by simply running the following commands in a terminal window: sudo apt-get update sudo apt-get dist-upgrade If the bug still exists, change the bug status from Incomplete to Confirmed. If the bug no longer exists, change the bug status from Incomplete to Fix Released. If you want this bot to quit automatically requesting kernel tests, add a tag named: bot-stop-nagging. Thank you for your help, we really do appreciate it. ** Changed in: linux (Ubuntu) Status: New = Confirmed ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete ** Tags added: kernel-request-3.2.0-22.35 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974765 Title: Drive not found since 3.2.0-21... kernel panic, unable to mount root fs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/974765/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
