Hi,

I'm currently running regression tests across various filesystems on linux
v7.0-rc3+ (HEAD=399af66228cfd7df79dc360810b6b673000f8090) before releasing
new fstests version. During my testing, I hit a crash several times with
ext4 on aarch64 (didn't hit it on other arches).

The console output showed a kernel warning about crypto/crypto_engine.c at
first:
  [  858.822866] WARNING: crypto/crypto_engine.c:55 at crypto_finalize_request+0x2bc/0x368 [crypto_engine], CPU#1: 15820000.crypto/587

then showed a bug at lib/list_debug.c and bad non-executable memory access:
  [  858.834134] kernel BUG at lib/list_debug.c:32!
  ...
  [  859.423056] Unable to handle kernel execute from non-executable memory at virtual address ffff80009c6a68b0
  ...

at last, it hit below warning when tried to make kdump:
  [  860.748125] Some CPUs may be stale, kdump will be unreliable.
  [  860.748294] WARNING: arch/arm64/kernel/machine_kexec.c:174 at machine_kexec+0x60/0x3c0, CPU#7: kworker/u50:4/65459

About more details please refer to the completed console output [1].

Thanks,
Zorro
