I am using Dell Inspiron 11 3000 2-in-1 (3147) too. I don't have any luck with acpi=off (Boot up process stuck at ath9k and irq problems) acpi = force/ht did not help either (Able to boot up)
I tried nolapic with some success (Sometimes it will not boot up, stuck at i2c_designware and irq 32 problems) I have also tried reboot=(every combination of flags) (Able to boot up) Currently, it will not shutdown/reboot/resume. Shutdown and reboot will hang at "will now halt/reboot" -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1341925 Title: [Dell Inspiron 11 - 3147] System will hang on reboot / poweroff Status in HWE Next Project: New Status in “linux” package in Ubuntu: Confirmed Bug description: CID: 201403-14888 Dell Inspiron 11 - 3147 While rebooting this system, it will stuck on the Ubuntu splash screen, caps lock LED will be not responding.
