Only with "acpi=off" the system started completely, and I was able to log in
into gdm, and later switch it off in normal way (crash8.txt).
With other parameters kernel panicked during the boot.

Of course I've mistaken.
The log from correct booting and shutdown is crash9.txt, not crash8.txt

However even in this run there is yet another kmemcheck error:
