dmesg using asus_laptop as module

after upgrading from kernel 4.3.3 to 4.4.0 had kernel panic issues

Previous versions of kernel (4.3.3 and earlier) with  asus_laptop and i915 built-in had no known issues

required loading i915 as module to trouble shoot .. on lenova SL500 .. 
discovered kernel panic could be mitigated by building asus_laptop as a module


have attached dmesg

determined that asus_laptop module now errors .. but will boot asus_laptop is a module .. of course  functions managed by this module .. e.g. laptop lid switch no longer function properly

I have the same problem. The patch at https://patchwork.ozlabs.org/patch/552082/ fixes it for me.
Comment 2 Derk te Bokkel 2016-01-14 17:38:34 UTC 
yes patching kernel source for 4.4.0 fixes the issue for me as well ..
how soon will this be applied to kernel sources?

The same problem here, with an Asus U45JC laptop. Affecting both linux-4.4.0 and 4.5-rc1. 4.3 and below are fine.
