Yes, inadequate shielding of the IO lines can cause spurious interrupts, and has certainly been in the past the main cause of hotplug storms. In this case, I suspect it is the firmware / firmware driver that is broken and causing the interrupt storm. Short of physically inspecting the signal lines, I'm not sure if you will get a definitive answer.
There is no mechanism to manually disable the hotplug interrupts without recompiling the code. There is magic in v3.10 that is meant to autodetect this, but it did not actually leave any telltale in your log... So I am beginning to suspect that it is not just a lot of hotplug events, but also the processing of each one that is slow. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1183089 Title: xorg freezes on macbook air unplugging thunderbolt display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1183089/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
