I'm experiencing similar file system corruption issues with my Sandisk Extreme 120GB SSD. All Ubuntu or Debian based Linux OSes I tried so far, including Ubuntu 12.04, as well as Fedora 16 and 17, report file system errors on bootup irregularly. After fsck and fixing the errors (or in case it boots normally), I get various segmentation faults and/or CRC errors for files. Trying 5 or 6 different distributions with the same results, I must conclude this may be a kernel issue.
I will update my SSD firmware in the hope that this solves the issue, but I doubt since the updated firmware supposedly only addresses TRIM issues (discard option in fstab). All distributions worked perfectly fine when booting them from a live USB stick. I checked my RAM using memtest86+ and it reports no errors. Also smartctl does not reveal any problems with the SSD. I managed to install and boot several 3.2 and later kernels from SSD, but when using synaptic for updates and installs I eventually get segmentation faults for synaptic, or the system doesn't boot anymore. It looks like something is corrupting the file system. Again, this happened with all new linux kernels 3.2 and above (see above list of distributions I tried). I do not have any issues with the SSD while running from a live USB stick. I can format the disk, install on it, chroot into it and install or modify things, but I can't get a stable system booting from the SSD. One of the common errors when the SSD doesn't boot is efidisk read error. But it also doesn't work with MBR formated SSD. I wonder if SSDs can be used with kernel 3.2 and above? I didn't try older kernel versions, though. Sorry I can't post more specific details, but if anybody is interested to get output of debugging commands with Ubuntu 12.04, I will try. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/992424 Title: ext4 filesystem errors on SSD disk To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/992424/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
