HI everyone, udev-237 seems to be crashing reproducibly on kernel 4.4.116+. I rebuilt it using gcc-7.3.0 and binutils 2.30, formerly using gcc-6.4.0 and binutils 2.29.1. This might as well be .config related, as I changed some stuff there as well.
The .config change is CONFIG_INTEL_TXT is not set -> CONFIG_INTEL_TXT=y. The .config for 4.4.117 is attached (no changes except the above). Afterwards I do not have any USB mouse available and "lsusb" stalls forever. Feel free to let me know what I could do to debug this further.
