I have an encrypted block device, `/dev/sda2', which is mounted as my root filesystem. I recently installed this system -- I've been away from Gentoo for awhile -- and used gentoo sources 2.6.31-r6. When the kernel upgrade rolled around, to 2.6.32-r7, I installed and rebooted and then my passphrase didn't work anymore. The error message:
Command failed: No key available with this passphrase. However, rebooting with my old kernel works fine so I'm not sure what the problem is. Could it be a different version of `cryptsetup'? When the device can't be opened on boot, I have the option to drop to a shell. I try to run `cryptsetup' and I get the same error -- so maybe that's my problem? Would different versions of `cryptsetup' be incompatible with devices encrypted by older versions? That seems brittle and dangerous to me. -- Jason Dusek
