[SOLVED] Cannot Boot After Upgrade
Upgraded today to the latest kernel update and now receive this message after reboot:
Waiting 10 seconds for device /dev/mapper/crypto-cryptoroot ...
Root device '/dev/mapper/crypto-cryptoroot' doesn't exist. Attempting to create it.
ERROR: Unable to determine major/minor number of root device '/dev/mapper/crypto-cryptoroot'.
You are being dropped to a recovery shell
I've bounced around and looked at a bunch of different threads, but can't seem to find anything relevant for troubleshooting. Any ideas? I have a LOT of business data on this machine that has not been backed up while I was away the last week without Internet. I would LOVE to have this be easily fixed haha. Thanks in advance for the help.

Re: [SOLVED] Cannot Boot After Upgrade
Uhm, first: downgrade the kernel and it should be possible to backup your data 
Which HOOKS are in your rc.conf?
Do you have a SATA HDD?
Do you have enough space on your partitions?

Re: [SOLVED] Cannot Boot After Upgrade
Solution found: Boot from Live CD, cryptsetup luksOpen /dev/sda2 crypto, mount cryptoroot, mount /boot partition, mount --bind /dev, /sys, and /boot mount point to the mounted cryptoroot. Chroot to the cryptoroot, then run mkinitcpio -p kernel26 to generate a new kernel image. Had to modify the HOOKS parameters in mkinitcpio.conf to include encrypt and lvm2. For some reason they had disappeared or maybe were not needed before or something. Marking [SOLVED].
