It bisected down to these two patches: fs-add-umh-argument-to-struct-kernel_clone_args.patch fs-stop-sharing-fs_struct-between-init_task-and-pid-1.patch That is, with all of the patches prior to fs-add-umh... the bug does not reproduce. With fs-add-umh... the 7.2.13-rc1 boot problem happens, and adding fs-stop-sharing... fixes the boot problem, but now I have the new message when suspending. dmesg context before and after the new message (should've included this in my previous email, sorry): [ 55.793416] PM: suspend entry (deep) [ 55.825734] Filesystems sync: 0.032 seconds [ 55.825812] (NULL device *): Direct firmware load for i915/kbl_dmc_ver1_04.bin failed with error -2 [ 55.826364] Freezing user space processes [ 55.827740] Freezing user space processes completed (elapsed 0.001 seconds) [ 55.827744] OOM killer disabled.
