Hello Thiago, the idea is to identify a pattern. Any event that triggers the
hang, hangs ecode repeating constantly, similar or same dmesg
warnings/errors/messages repeating just before the hang happening, etc.

So far first error state hangs on render ring hangs due to the ELSP comment #3:
  hangcheck stall: yes
  hangcheck action: dead
  hangcheck action timestamp: 4368325000, 304160 ms ago
  ELSP[0]:  pid 6476, ban score 0, seqno       31:00e19461, emitted 306200ms
ago, head 00000000, tail 00000078

The second hangs on blitter ring:
  hangcheck stall: yes
  hangcheck action: active head
  hangcheck action timestamp: 4333247497, 318116380 ms ago
  ELSP[0]:  pid 2065, ban score 0, seqno        1:00872687, emitted 318102344ms
ago, head 00003f10, tail 00003f60

The third and forth on render ring again but these reach further than the
first:
  hangcheck stall: yes
  hangcheck action: dead
  hangcheck action timestamp: 4358891744, 156332 ms ago
  ELSP[0]:  pid 3457, ban score 0, seqno        e:00993440, emitted 159048ms
ago, head 00000000, tail 00000080
  ELSP[1]:  pid 2463, ban score 0, seqno        1:00993441, emitted 158976ms
ago, head 00000080, tail 000000f8
  Active context: kmail[3457] user_handle 3 hw_id 14, ban score 0 guilty 0
active 0

and 

  hangcheck stall: yes
  hangcheck action: dead
  hangcheck action timestamp: 4373527248, 210700 ms ago
  ELSP[0]:  pid 92664, ban score 0, seqno       14:0143a658, emitted 212956ms
ago, head 00000000, tail 00000080
  ELSP[1]:  pid 4343, ban score 0, seqno        1:0143a659, emitted 212900ms
ago, head 00000180, tail 000001f8
  Active context: chrome[92664] user_handle 3 hw_id 20, ban score 0 guilty 0
active 0

Maybe it would be possible to get a dmesg with debug info since it seems to
repeat. Just add drm.debug=0x1e log_bug_len=2M to the grub.
