It took 14 steps, but finally here is the possible culprit:
19809c2da28aee5860ad9a2eff760730a0710df0 is the first bad commit

mm, vmalloc: use __GFP_HIGHMEM implicitly
__vmalloc
Unfortunately it's not working, but the bug is at another codeline, so
maybe another problem? Or the same problem is in the code multiple
times?

Title:
DVB Card with SAA7146 chipset not working
Status in l
Public bug reported:
After upgrading to 17.10 (from 16.04 with 4.4 kernel) my PCI DVB card
Terratec Cinergy DVB-1200 with SAA7146 chipset is not working anymore.
There is a kernel bug message while booting and no /dev/dvb device is
created. Tried also with newest mainline 4.14 kernel - same error.
Unfortunatly the same problem:

I've tried some of the mainline kernels and finally got to this situation:
last working kernel: v4.11.12 mainline build [1]
first non working kernel: v4.12-rc1 mainline build [2]
Hope that will help to find the bug.

Thanks for your work, but could you build the kernel for i386 platform,
as my system (Atom D2700) does not support amd64 due to bios
restrictions?
