It seems like this problem is somehow related to the integrated NVidia Optimus technology of my laptop.
If I change the BIOS settings (Graphics Device -> Integrated Graphics, OS Detection for NVidia Optimus -> Disabled) to use the integrated graphics card only, the above SATA errors disappear. Re-enabling the Optimus technology in the BIOS these error messages show up again. So the problem is clearly correlated with the NVdidia Optimus technology. Does that help? Why would the graphics device provoke SATA errors? Btw, if I set "OS Detection for NVidia Optimus" to "Enabled" in my BIOS settings, Ubuntu automatically enables Optimus technology. Is that wanted? As far as I know Ubuntu does not support Optimus yet and hence it should not enable it automatically. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/888764 Title: SATA link frequently resetting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/888764/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
