--- Comment #8 from Armando Antonio <armando.antoniox.mora.reos at intel.com> ---
Hello, I ran the following test cases on KBL with latest configuration, without
Guc and still falling.

Test cases
igt at gem_exec_whisper@contexts-forked
igt at gem_exec_whisper@fds-forked
igt at gem_exec_whisper@hang-chain-forked

Same output:

(gem_exec_whisper:1378) igt-aux-CRITICAL: Test assertion failure function
sig_abort, file igt_aux.c:444:
(gem_exec_whisper:1378) igt-aux-CRITICAL: Failed assertion: !"GPU hung"
Stack trace:
  #0 [__igt_fail_assert+0x101]
  #1 [sig_abort+0x3a]
  #2 [killpg+0x40]
  #3 [__wait+0x1e]
  #4 [igt_waitchildren+0x68]
  #5 [whisper+0x1f9]

  #7 [main+0x23]
  #8 [__libc_start_main+0xf1]
  #9 [_start+0x29]

Subtest fds-forked failed.
