Can you tell exactly where it stops during the boot ? Or take a photo of the screen ?
I'll attach a photo shortly.
In parallele, could you try (without VMAP_STACK) increasing CONFIG_THREAD_SHIFT to 14 ? It will double the size of the stacks.
I can confirm that with CONFIG_THREAD_SHIFT=14 the G4 runs good again with INLINE KASAN + KASAN_VMALLOC enabled (as seen in attached dmesg). No KASAN hit at raid6_pq, no poblem with btrfs. Though with CONFIG_THREAD_SHIFT=14 + OUTLINE KASAN + KASAN_VMALLOC I still get this KASAN hit at raid6_pq. -- You are receiving this mail because: You are watching the assignee of the bug.
