I haven't been able to reproduce the problem after running fsck on /dev/sda5.
I'm attaching an excerpt from my syslog which includes the errors I was getting (I guess they didn't show up in the logs sent by apport). I still intend to test newer kernels and run other checks to see if it's a hardware or software problem. ** Attachment added: "older syslog, demonstrating the errors" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1649584/+attachment/4792244/+files/syslog_dec_10_11.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1649584 Title: Kernel update 3.13.0-105 causes SATA errors that end up remounting partitions as read-only To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1649584/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
