Fedora :: Command Failed: Can Not Access Device?

I updated quite a lot - kernel, selinux policies, initscripts, glibc and a lot more - and after reboot one filesystem does not mount. It says:Command failed: Can not access device... and asks for password. This is: RAID -> LVM (mirrored) -> LUKS -> ext3. Similar filesystem (raid->lvm(not mirrored)->luks->ext3) mounts fine. Mounting the problematic system by hand works fine. During boot, the lvm blockdev is named by UUID in crypttab, and the name used in fstab.

Of course I removed it from fstab to boot now. I tried downgrading initscripts so far, will try others. What I also noticed is that the emergency shell (bash) complains about something, I'd need to write it down next time I reboot; also "lvs" fails when / is ro, but maybe that's normal, dunno.Googling for the error message brought something about cryptsetup, but I didn't upgrade it (there is no upgrade available), and all I gather from it is that the error message might really mean something else, like device is already mapped.

It is probably something related to lvm mirrors, maybe also to luks, though the only related package in the list is the kernel, maybe the module-init-tools. SELinux seems not to be the cause, booting with permissive has the same problem. What I wrote above, leads me to thinking that luks is trying to set up lvm mirrors in parallel as they have the same uuid, but a) later during boot the mapping name is not there b) I have no idea what reads crypttab
