This is my first x64 Ubuntu installation. I noticed this problem with earlier kernels but it was not critical to me because it did not cause freeze PC, only slow reactions and lags when working with files on HDD.
I installed kernel 3.18 and error messages are same, mostly at computer startup. Computer beeps fast 3 times and then I am not able to use HDD anymore. Every action gives me back IO error. I can only turn off computer hard way by holding power button. Computer is half year old, so I dont think it is HDD faulty. HDD is SSHD, combination of 8GB SSD and 1000GB HDD. ** Tags added: kernel-bug-exists-upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1400850 Title: failed command: READ DMA EXT To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1400850/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
