Summary: LUKS+LVM install ok, kernel panic at boot
Product: Mageia
Version: 1
Platform: x86_64
OS/Version: Linux
Status: NEW
Severity: critical
Priority: Normal
Component: Installer
AssignedTo: bugsquad-odJJhXpcy38dnm+***@public.gmane.org
ReportedBy: fathom-***@public.gmane.org


Description of problem:
I wanted to install mageia with the following disk setup:
-4GiB to swap
-250MiB to /boot with ext4 fs
-LVM physical with encryption (rest of my hd)
--12 GiB to / with ext4 fs
--rest to /home with ext4 fs

Installation seems ok. Tried from dual-arch iso with and without additional
network sources to use.
On boot, after password given successfully to LUKS, kernel panics.

Here is the last few lines:
Making device-mapper control mode
waiting for device sda6 to appear (timeout 1 min)
waiting for device sda6 to appear (timeout 1 min)

As a workaround, try creating the lvm physical volume without
encryption, and then encrypting the filesystems within the
logical volumes. I haven't tried using an encrypted /, but
have done this with /home.
