commit d52888aa2753 ("x86/mm: Move LDT remap out of KASLR region on
5-level paging") changed PAGE_OFFSET from 0xffff880000000000 to
0xffff888000000000.
crash can't open such with CONFIG_RANDOMIZE_BASE=n:
crash: read error: kernel virtual address: ffff888ffe605024 type: "tss_struct ist
array"
Edit defs.h:
-#define PAGE_OFFSET_2_6_27 0xffff880000000000
+#define PAGE_OFFSET_2_6_27 0xffff888000000000
And this works for me.
(d52888aa2753 has also been included in 4.14.84)
Thanks
