Hi, On recent next I see bugs during boot (after bringing up user-space or during reboot): kernel BUG at ../mm/vmalloc.c:470! On all my boards. On QEMU I see something similar, although the message is "Internal error: Oops - undefined instruction: 0 [#1] ARM", The calltrace is: [ 34.565126] [<c0275c9c>] (__free_vmap_area) from [<c0276044>] (__purge_vmap_area_lazy+0xd0/0x170) [ 34.573963] [<c0276044>] (__purge_vmap_area_lazy) from [<c0276d50>] (_vm_unmap_aliases+0x1fc/0x244) [ 34.582974] [<c0276d50>] (_vm_unmap_aliases) from [<c0279500>] (__vunmap+0x170/0x200) [ 34.590770] [<c0279500>] (__vunmap) from [<c01d5a70>] (do_free_init+0x40/0x5c) [ 34.597955] [<c01d5a70>] (do_free_init) from [<c01478f4>] (process_one_work+0x228/0x810) [ 34.606018] [<c01478f4>] (process_one_work) from [<c0147f0c>] (worker_thread+0x30/0x570) [ 34.614077] [<c0147f0c>] (worker_thread) from [<c014e8b4>] (kthread+0x134/0x164) [ 34.621438] [<c014e8b4>] (kthread) from [<c01010b4>] (ret_from_fork+0x14/0x20) Full log here: https://krzk.eu/#/builders/1/builds/3356/steps/14/logs/serial0 https://krzk.eu/#/builders/22/builds/1118/steps/35/logs/serial0 Bisect pointed to: 728e0fbf263e3ed359c10cb13623390564102881 is the first bad commit commit 728e0fbf263e3ed359c10cb13623390564102881 Author: Uladzislau Rezki (Sony) <urezki@xxxxxxxxx> Date: Sat Jun 1 12:20:19 2019 +1000 mm/vmalloc.c: get rid of one single unlink_va() when merge Boards: 1.
