1) system1

2) system2
Code: 14000012 f9400273 b4000213 d1002274 (b9402280)
And the upstem report in #15,
Code: 14000003 f9400273 b4000213 d1002274 (b9402282)
The code snippet should be the following in __d_lookup(): fs/dcache.c
ffffffc0001aae68: 14000003 b ffffffc0001aae74
<__d_lookup+0x84>
*
* See Documentation/filesystems/path-lookup.txt for more details.

ffffffc0001aae78: b9402282 ldr w2, [x20,#32]
#faulted instruction
Then the problem should be caused by bad pointer of dcache.
