Bug ID: 92335
Summary: [HSW Regression] Null pointer deference in
intel_mmio_flip_work_func
Product: DRI
Version: DRI git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: DRM/Intel
Assignee: intel-gfx-bugs at lists.freedesktop.org

journalctl -b-1
HSW 4770, instant freezes for about a week now with drm-intel-nightly, so far
when ordinarily browsing with Chromium (full HW acceleration). No indication
what specifically causes it.
journalctl shows an earlier WARN_ON_ONCE(!ppgtt) as well, only since yesterday
so probably unrelated.
