LMDE 2013rc - Strange boot behaviour

[kalinik]

Hi,
I've just installed latest LMDE 2013 -rc and installation went just fine, BUT after i "tuned" my new system and had to restart, it boots in :

"filesystem is read only"

blah-blah-blah and stops.
I remounted it manually read-write and looked at /etc/fstab - everything looks fine, but the problem exist every time.
Here is my /etc/fstab:

Code: Select all

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

proc    /proc   proc    defaults        0       0
#Entry for /dev/sdc1 :
/dev/sdc1       /       ext4    relatime,errors=remount-ro,user,data=writeback  0       1
#Entry for /dev/sdc5 :
/dev/sdc5       /home   ext4    rw,noatime,relatime,data=writeback      0       1
#Entry for /dev/sdb1 :
UUID=ACF04A91F04A61A6   /media/wd       ntfs-3g defaults,locale=en_US.UTF-8     0       0
#Entry for /dev/sdc4 :
UUID=EA1416101415DFFD   /media/win      ntfs-3g defaults,locale=en_US.UTF-8     0       0
#Entry for /dev/sdc7 :
UUID=fa42b721-b41b-4556-8933-ff9934d7815a       swap    swap    sw      0       0
#HOME 2
/dev/sda5 /media/home2  ext4    rw,noatime,relatime,data=writeback      0       0
#USR2
/dev/sda6 /media/usr2  ext4     noatime,relatime,user   0       0
#root2
/dev/sda1 /media/root2 ext4     noatime,relatime        0       0

I also checked the UUID-numbers (just in case) for every drives - they are correct. Updated initramfs and grub - no luck.
The only way to boot normally is to write "rw" instead of "ro" at GRUB_CMDLINE_LINUX_DEFAULT=rw... etc. That helps but my other Debian Wheezy system does not need to write down "rw" at grub.
The fstab files are almost identical but LMDE won't boot.

Where is the problem ?

I checked hard disk(s) - all fine
I checked for other hard disk related errors - all fine/no errors
I checked for system errors - nothing related to boot process(es) or hard disk(s)

dmesg also looks fine (checked every reboot) - see attached file

what exactly did your tuning consist of?

what exactly did your tuning consist of?

Nothing too special. Just some tweaking at boot order services, stopping some of them, preload, readahead-fedora ... etc. System boots around 20 sec. mark and stays rock stable at the moment, except the boot !
Same config as my pure Debian Testing where there is no problems at all.
I wrote "rw" flag at /etc/default/grub and it boots but that's not recommended ,so I continue to search where the problem is.

Maybe some cryptsetup maintainer could shed some light on how this script in general and canonical_device specifically are supposed to behave when root
and/or swap are not meant to be encrypted?
update-initramfs -u -k all returns that error:
cryptsetup: WARNING: failed to detect canonical device of /dev/sdc1 << that's the root partition, nothing wrong

Currently I'm out of ideas
