i915kms on Lenovo T510

[M&S - Krasznai András]

I had no luck until this morning, ran into a installation issue. There was some problem with the rescue component, and make installworld found a missing file, so I restarted compilation today (after refreshing my /usr/src) – I saw a message from Bryan Drewery about this issue which is patched now.

Hi

explicitly specifying the path for the modules did not help.

Hans Peter Selansky looked at the Fatal trap and suggested to compile a GENERIC kernel with debugging support so we can see  the backtrace, I am now compiling. It will take 3-4 hours so I will report the results tomorrow.

Great! Thanks. We really appreciate you're taking the time to track this down.

Thanks! Seems like Arrandale, predecessor to Sandy Bridge.

To OP:
Can you put
dev.drm.drm_debug=-1
in /boot/loader.conf and send a dmesg output? (or /var/crash/core.txt.X)

One more thing to check is if the correct drm module is loaded. Safest is to do
kldload /boot/modules/drm.ko
kldload /boot/modules/i915kms.ko
and with kldstat -v check that the modules are loaded from /boot/modules and not /boot/kernel/
