I've just installed Windows 8 alongside my already existing Ubuntu 13.04 installation on my laptop. As expected, I couldn't boot into Ubuntu right after Windows installation, but fixed that using EasyBCD. Now I can boot into Ubuntu again. However, since the installation, my Ubuntu partition (sda1) gets remounted read-only after about 2 minutes since boot.
Here is the relevant output of
[ 118.017469] EXT4-fs error (device sda1): ext4_ext_search_left:1315: inode #14287139: comm flush-8:0: ix (13130) != EXT_FIRST_INDEX (0) (depth 1)! [ 118.017475] Aborting journal on device sda1-8. [ 118.017723] EXT4-fs (sda1): Remounting filesystem read-only [ 118.017744] EXT4-fs error (device sda1) in ext4_da_writepages:2446: IO failure [ 118.017958] EXT4-fs (sda1): ext4_da_writepages: jbd2_start: 11261 pages, ino 14287139; err -30
Already ran fsck and gparted's file system check from a Live CD which told me, that it indeed had fixed some errors, but the problem still persists.
Any help is appreciated.
Update: Okay, this is weird, I just found out, that this happens as soon as I start the Google Chrome browser. So it seems to be related to this question which unfortunately still has no answer.
