I'm not sure if this is the right place to ask my questions, but I found
very sparse documentation when it comes to solve problems with kexec.
I'm running an arch linux setup on my Macbook Pro 8,1 (Kernel
3.6.7-1-ck) with an i915 vga adapter (Intel HD Graphics 3000) and I try
to use kexec with systemd.
Systemd uses a service file to load the new Kernel image before
ExecStart=/sbin/kexec -l /boot/vmlinuz-linux-ck \
I use a system with an encrypted root partition, but I ran into the
exact same issue with my old setup (without encrypted root).
But when I issue the kexec call I can read the line
"Starting new kernel" and then my screen is garbled. I read a lot about
issues with the vga console, so I tried to reach my system by ssh, but
it didn't work.

Some more info:

MODULES="ahci libahci ehci-hcd uhci-hcd ext3 ext4 vfat"
HOOKS="base udev keymap fsck autodetect pata scsi sata usbinput encrypt
lvm2 uresume filesystems"
Does anyone have a hint how I could "debug" this issue or get kexec to
work on my system?
