System freezes on loading screen after update

Pio6 · 04-19-2015, 12:10 PM

Hi. After updating my elementary OS Freya 64 bit using update manager it freezes on loading screen. The only thing I see is elementary OS logo and blinking animation and nothing happens. My hard drive seems to be idle. First time after update I saw some blinking gray stripes on my screen and I though i might be graphics issue but it never happened again. When I press ESC or ctrl + alt + F1 on loading screen I see this message repeating a few times: "scanning for btfrs filesystems end request: i/o error, dev sr0, sector 0" and it freezes. When I try to enter recovery mode I see some messages and this one at the end: "Btfrs info (device sda8): disk space caching is enabled" and nothing else happens.
What causes the problem and how to fix this?

Have a look at this: https://btrfs.wiki.kernel.org/index....ge/btrfs-check

and this:

Elementary OS recovery mode started to work but I dont know why, because I didnt do anything - it just worked. It also appears that I can mount this btrfs partition and use it. I tried btrfs check --repair:

Code:

sudo btrfs check --repair /dev/sda8
enabling repair mode

Btrfs v3.16.2+201

and it didn't do anything so I also tried sudo btrfsck --repair --init-csum-tree.

attempting to repair backref discrepency for bytenr 597393408
Backrefs don't agree with each other and extent record doesn't agree with anybody, so we can't fix bytenr 597393408 bytes 16384
failed to repair damaged filesystem, aborting

After this I tried to boot elementary OS and it still freezes but now LEDs on my keyboards are blinking and when I press ESC I can see a few times repeated word 'panic' and some hex codes. When I try to run recovery mode I see this:

Code:

kernel offset 0x0 from ffffffff81000000 relocation range end kernel panic - not syncing: attempted to kill init! exit code=0x000000100

Is there something else I can do?

Try to make an backup of your important data.
You should better use a filesystem, which is more stable: e.g. ext4.
