Yes, I use laptop-mode-tools 1.65-2

I'm running on Dell Latitude E6520 with SSD 256GB.

I tried five reboots today, and one time the startup was successful
(read-write root). The rest startups was with read-only root.

LVs with `E' prefix uses LUKS

bobek:~# cat /etc/crypttab 
# <target device> <source device> <key file> <options>
root   /dev/mapper/ssd-Eroot    none    	discard,luks
swap   /dev/mapper/ssd-Eswap    /etc/keys/mykey discard,luks
home   /dev/mapper/ssd-Ehome    /etc/keys/mykey discard,luks
data   /dev/mapper/ssd-Edata    /etc/keys/mykey discard,luks


I have removed ipmitool, so the service ipmievd is away (there was errors about
inserting ipmi_si module).
The log is now shorter, error messages at start are:

Maybe the problem is about some race condition?
