--- Begin Message ---Package: initramfs-tools Version: 0.120 Severity: important Dear Maintainer, I have a hard time wrapping my head around this bug, feel free to assign somewhere else. We have started upgrading some of our production VMs to Jessie. The testsystems worked fine, but I have hit the following bug for the second time on a production VM now. - dist-upgrade works flawlessly - on first boot into Jessie I get an immediate (<1s) kernel-panic (see attached screenshot) about being unable to find the root fs. Unfortunately I'm unable to get the full boot log, since I don't have a serial console there and kernel messages scroll by too fast. - To fix the issue I have to boot into the old Wheezy kernel (3.2.0-4-amd64) in grub and regenerate the initrd for the Jessie kernel # update-initramfs -k 3.16.0-4-amd64 -u Then it works fine. Now comes the interesting part ... I have saved the broken initrd for later analysis The compressed size is marginally different (broken being 3k smaller) -rw-r--r-- 1 root root 14339199 Apr 28 13:59 initrd.img-3.16.0-4-amd64 -rw-r--r-- 1 root root 14338898 Apr 28 13:58 initrd.img-3.16.0-4-amd64.broken The uncompressed size is the same root@lxmhs63:/tmp# zcat /boot/initrd.img-3.16.0-4-amd64.broken > initrd.img-3.16.0-4-amd64.broken root@lxmhs63:/tmp# zcat /boot/initrd.img-3.16.0-4-amd64.broken > /tmp/initrd.img-3.16.0-4-amd64.broken root@lxmhs63:/tmp# ls -la /tmp/initrd.img-3.16.0-4-amd64* -rw-r--r-- 1 root root 45304832 Apr 28 14:44 /tmp/initrd.img-3.16.0-4-amd64 -rw-r--r-- 1 root root 45304832 Apr 28 14:44 /tmp/initrd.img-3.16.0-4-amd64.broken The checksum is different root@lxmhs63:/tmp# md5sum /tmp/initrd.img-3.16.0-4-amd64* 7b24aa901b697dc5dfdbad03bd199072 /tmp/initrd.img-3.16.0-4-amd64 5e467c0a49afa4ddae315cc6e818d7ac /tmp/initrd.img-3.16.0-4-amd64.broken Now comes the puzzling part ... the _content_ of the initrd is exactly the same root@lxmhs63:/tmp# mkdir broken && cd broken && cpio -id < ../initrd.img-3.16.0-4-amd64.broken 88486 blocks root@lxmhs63:/tmp/broken# cd .. root@lxmhs63:/tmp# mkdir ok && cd ok && cpio -id < ../initrd.img-3.16.0-4-amd64 88486 blocks root@lxmhs63:/tmp/ok# cd .. root@lxmhs63:/tmp# diff -urN broken ok I will try to capture a screenlog on the next upgrades, maybe there is something interesting in there.
