Summary: Issues when loading intel kernel module i915 on boot
taints kernel
QA Contact: intel-gfx-bugs at lists.freedesktop.org
Severity: normal
Classification: Unclassified
OS: All
Reporter: sacoo2 at hotmail.com
Hardware: Other
Status: NEW
Version: unspecified
Component: DRM/Intel
Product: DRI
I am running debian wheezy on a Supermicro X7SPA-HF board, instead of the
distribution provided kernel I am using the current stable (3.15).
Every time after booting the system there are several error on the i915 that
left the kernel in tainted state, hence making it more difficult to debug other
issues with other modules that appear later.
I have seen this issue on most of the 3.15 rc, and finally seems that the issue
made into stable.
On the server I don't have any X server running, and there are few running
processes.
Regards,
Joan
