Bug 17381

Summary:	Module intel-agp causes page fault
Product:	Drivers	Reporter:	Sebastian Herbst (master.of.herb)
Component:	Video(DRI - Intel)	Assignee:	drivers_video-dri-intel (drivers_video-dri-intel)
Status:	CLOSED CODE_FIX
Severity:	blocking	CC:	akpm, jbarnes
Priority:	P1
Hardware:	All
OS:	Linux
Kernel Version:	2.6.35.3	Subsystem:
Regression:	No	Bisected commit-id:
Attachments:	Config with apg and intel-apg compiled statically into the kernel

Description Sebastian Herbst 2010-08-29 23:20:43 UTC

Whenever intel-agp is loaded (via udev or manually using insmod)
the kernel is trapped with a page fault. Unfortunately I have no idea
how to save the sometimes showing stack backtrace into a file.

Compiling the module statically into the kernel causes to immediately crash
the kernel when it's loaded.

My hardware is Lenovo X300. The affected configs are attached to this bug
report. If you need further information on this issue, I'll be happy to supply
it here.

Is this a regression?  Was 2.6.34 OK?

Thanks.

Comment 3 Dave Airlie 2010-12-12 08:02:02 UTC

can we get a dmesg from a booted kernel?

Timeout waiting for update (plus I think it's fixed).
