Bug ID: 99295
Summary: [Regression BDW] kernel panic in Intel i915 module,
complete system freeze in 4.10-rc2
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: blocker
Priority: medium
Component: DRM/Intel
Assignee: intel-gfx-bugs at lists.freedesktop.org

So I am running kernel version 4.10-rc2 on Ubuntu and several times my computer
has become completely unresponsive and requires a forcible removal from a power
supply. We're talking just a complete and total freeze, all IO devices become
utterly unresponsive. Each time, a similar message citing a kernel NULL pointer
dereference within the i915 module is generated in the syslog:
Any insight would be appreciated. This is rather critical, as it causes a
severe system failure.
The following is the message from the syslog:
