Package: intel-microcode Version: 2.20140624.1 Severity: critical Justification: breaks the whole system
hi I have installed a small wheezy system, and then promptly upgraded it to jessie. This system has rootfs crypted with cryptsetup (altogh I am not sure this is relevant). I have two kernel currently in /boot, 3.14-2-amd64 and 3.2.0-4-amd64, I can boot the system with the latter, but not with the former. When I try to boot using 3.14-2-amd64 , the scripts in initrd complain that it cannot find the rootfs. I tried to investigate the problem, and found this startling fact. Usually initrd.img is a CPIO archive, compressed with GZIP. Instead, initrd.img-3.14-2-amd64 is a CPIO file but not compressed, and it seems to contain only this file $ cpio -t < /boot/initrd.img-3.14-2-amd64 kernel kernel/x86 kernel/x86/microcode kernel/x86/microcode/GenuineIntel.bin (even if initrd.img-3.14-2-amd64 is itself quite large, roughly 14MB). After some fiddling, I noted that if I delete the file /usr/share/initramfs-tools/hooks/intel_microcode and regenerate initrd.img-3.14-2-amd64 then it is fine. Unfortunately I cannot understand why it is broken. You may find the broken initrd in http://mennucc1.debian.net/tmp/initrd.img-3.14-2-amd64 I attach 3 files, that are the output of $ update-initramfs -v -u -k 3.14-2-amd64 3.14~no~microcode : the output when /usr/share/initramfs-tools/hooks/intel_microcode is deleted 3.14~with~microcode : the output when /usr/share/initramfs-tools/hooks/intel_microcode is present 3.14~with~microcode~xz : the output when I add 'set -zx' to /usr/share/initramfs-tools/hooks/intel_microcode a. -- System Information: Debian Release: jessie/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 3.2.0-4-amd64 (SMP w/2 CPU cores) Locale: LANG=it_IT.UTF-8, LC_CTYPE=it_IT.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages intel-microcode depends on: ii iucode-tool 1.0.3-1 Versions of packages intel-microcode recommends: ii initramfs-tools 0.116 intel-microcode suggests no packages. -- no debconf information -- Andrea Mennucc "E' un mondo difficile.
