So, after a few days of further testing i'm convinced that the 3.8.0-29 version of the kernel still has some problems.
yesterday, i got the black screen with a blinking underscore again, but after rebooting i got a screen with "/ has to be checked for errors", done, automatic reboot, login worked. then again, a few minutes ago something went wrong again (as you can see in the attached dmesg2.out) and the filesystem was readonly again (well, in fstab is configured to mount as ro when an error occurs, thats no surprise than). i will now try using the 3.8.0-30.43 kernel as proposed by Joseph. ** Attachment added: "dmesg2.out" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1215269/+attachment/3785868/+files/dmesg2.out -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1215269 Title: Unable to boot after kenel update (3.8.0-29). Status in “linux” package in Ubuntu: Incomplete Bug description: After installing the updated kernel (3.8.0-29), I was suddenly unable to boot. I will experience a frozen screen for several seconds, followed by an error claiming that my installation partition cannot be found. However, the 3.8.0-27 kernel seems to work just fine. I attempted an fsck, but no errors were found. I then removed the -29 kernel completely (sudo apt-get purge, followed by sudo update-grub), reinstalled it, but ended up with the same result. Now for some system details: I'm using Ubuntu 13.04 x86_64, with all the latest stable updates installed. My machine's hard drive is controlled by an Intel ICH9R/DO/DH SATA AHCI Controller chipset, currently set to AHCI mode (as opposed to IDE or RAID mode). Ubuntu is stored on an exteded partition, which is formatted with EXT4 (/dev/sda6). My first three partitions are Windows installs, each with formatted with NTFS. Also, I have /dev/sda7 as my Swap partition. If there are anymore details I can provide, please don't hesitate to ask.
