This bug also appears on Acer Aspire E15 Laptops (E5-511-P7AT) and (E5-511-P01P) on 14.04.3 Trusty with kernel 3.19.0-28.
If dw_dmac and dw_dmac_core are not blacklisted, everytime on Shut Down or Reboot comes a black screen and the fan starts spinning like crazy every +-20 seconds, but the machine doesn't shut down or reboot. I hope this issue will be fixed for the next LTS 16.04 ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1501580 Title: Workaround for dw_dmac causing random hang when booting To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1501580/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
