this seems to be wrong:

From my machine:

 2    1 0xffffffff817e4000 aee0     sem.ko
 3    1 0xffffffff81a12000 9db3     linprocfs.ko
 4    1 0xffffffff81a1c000 587a5    linux.ko
 5    1 0xffffffff81a75000 3900     ums.ko
 6    1 0xffffffff81a79000 2b0d     uhid.ko
 7    1 0xffffffff81a7c000 1b7a1    ng_btsocket.ko
 8    1 0xffffffff81a98000 ba58     netgraph.ko
 9    1 0xffffffff81aa4000 118b     ng_bluetooth.ko
10    1 0xffffffff81aa6000 a9f3     fuse.ko
11    1 0xffffffff81ab1000 69298    i915kms.ko
12    1 0xffffffff81b1b000 1ba2     iicbb.ko
13    4 0xffffffff81b1d000 1ddb     iicbus.ko
14    1 0xffffffff81b1f000 1cd5     iic.ko
15    1 0xffffffff81b21000 32386    drm2.ko
16    1 0xffffffff81b54000 241      acpi_call.ko

So, why did drm.ko and i915.ko make it into your kernel?

I did not touch this machine since 16.07.12.

Maybe your patches affected something. Can you download a fresh source
tree?
