            Bug ID: 95372
           Summary: [BAT BYT] Sporadic failure from
                    igt/gem_exec_flush at basic-batch-kernel-default-cmd
           Product: DRI
           Version: DRI git
          Hardware: All
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Intel
          Assignee: intel-gfx-bugs at lists.freedesktop.org
          Reporter: matthew.d.roper at intel.com

This test seems to fail sporadically with a couple different failure errors. 
The most common one is:

  (gem_exec_flush:6041) ioctl-wrappers-CRITICAL: Test assertion failure
function gem_execbuf, file ioctl_wrappers.c:589:
  (gem_exec_flush:6041) ioctl-wrappers-CRITICAL: Failed assertion:
__gem_execbuf(fd, execbuf) == 0
  (gem_exec_flush:6041) ioctl-wrappers-CRITICAL: error: -22 != 0

But looking through the CI history, it appears there's also sometimes:

  (gem_exec_flush:6131) CRITICAL: Test assertion failure function batch, file
gem_exec_flush.c:456:
  (gem_exec_flush:6131) CRITICAL: Failed assertion: map[i] == cycles + i
  (gem_exec_flush:6131) CRITICAL: error: 0xabcdabcd != 0x3
