Description of problem: I did an upgrade from Fedora 14 to Fedora 15 using preupgrade. When the Fedora 15 2.6.40.3-0.fc15.x86_64 kernel is now booted, I get this error: modprobe: FATAL: Could not load /lib/modules/2.6.40.3-0.fc15.x86_64/modules.dep: No such file or directory device mapper: reload ioctl failed: Invalid argument Failed to setup dm-crypt key mapping for device /dev/sda2. Check that the kernel supports aes-xts-plain64 cipher (check syslog for more info). Failed to read from key storage. Then it is asking for the password for the encrypted disk: Password for /dev/sda2 (luks-faa...):******* When I enter the password I get: [ 565.358082] device-mapper: table: 253:0: crypt: unknown target type And then the modprobe message as above again, and the whole thing repeats. Version-Release number of selected component (if applicable): 2.6.40.3-0.fc15.x86_64 How reproducible: always Steps to Reproduce: 1. Switch the laptop on Actual results: Repetitive request for file system password in text mode. Expected results: Request for file system password in a graphical window. After entering this, a normally booted system Additional info: Initially something went wrong with the preupgrade. I booted from a Fedora 15 DVD to 'rescue the system' and completed the upgrade with preupgrace-cli. I tried to boot a remaining F14 kernel, but entering the file system passwords is half broken. I have to type letters several times before they appear (both in text and graphical mode). I think I manages once or twice to boot the system after the upgrade using a F14 kernel.
Maybe these bugs are related: Bug #712865 - Encrypted system fails to load Bug #672848 - Unable to set password to unlock encrypted disk Bug #698209 - Kernel panic - unable to mount root fs Bug #716291 - Not all LUKS partitions are unlocked during boot process Bug #708574 - Boot fails: Starting /home aborted because dependency failed Bug #708456 - Need to disable plymouth to enter password for encrypted / and swap partitions Bug #731261 - System does not boot, hangs on password request Bug #732281 - System boot failed after creating new initramfs w/ initial distro kernel and other Bug #589390 - aesni-intel module breaks booting off encrypted root
I described the problem here as well: http://forums.fedoraforum.org/showthread.php?t=268835 I can boot from an old Fedora 14 kernel (2.6.35.13-92.fc14.x86_64) if I remove the rgb boot parameter. Though I have to provide the file system password twice. And entering the second password goes difficult, because sometimes I have to hold the key pressed long before a '*' appears on the screen.
I solved this problem by booting an old Fedora 14 kernel. yum erase of the fedora 15 kernel. yum install --releasever=15 of a new fedora 15 kernel. After this the system booted without problems.
