There are a few similar reports in this bugzilla, but please note that my dmesg ends with Oops. So probably it gives more info. Adding tag into "Whiteboard" field - ReadyForDev *Status is correct *Platform is included *Feature is included *Priority and Severity correctly set *Logs included *** Bug 100076 has been marked as a duplicate of this bug. *** |

Created attachment 130221 [details] dmesg With intel_iommu=on in command line, GPU hangs at boot, after which, the entire machine freeze happens. I managed to retrieve logs by using "linux=single" - it helps to avoid the full machine freeze sometimes (maybe because X doesn't start then), but its still a blank screen. intel_iommu=on,igfx_off fixes the problem but I guess this will not allow to pass-through the video card, is this correct?
