On CI_DRM_3062, all the machines running the test igt@gem_pwrite_pread@display-copy-correctness started failing it with the following error:

(gem_pwrite_pread:1499) CRITICAL: Test assertion failure function test_copy, file gem_pwrite_pread.c:170:
(gem_pwrite_pread:1499) CRITICAL: Failed assertion: igt_ioctl((fd), ((((1U) << (((0+8)+8)+14)) | ((('d')) << (0+8)) | (((0x40 + 0x29)) << 0) | ((((sizeof(struct drm_i915_gem_execbuffer2)))) << ((0+8)+8)))), (&execbuf)) == 0
(gem_pwrite_pread:1499) CRITICAL: Last errno: 5, Input/output error
(gem_pwrite_pread:1499) CRITICAL: error: -1 != 0

Nothing has changed in the kernel, so it seems to be an IGT bug introduced by one of these commits:

meson: Bump required version to 0.40
meson: Minimal README update
meson: igt_frame also needs pixman
meson: add manpage support
meson: detect cc flags
meson: Use static libs to handle IGT_LOG_DOMAIN.
meson: Don't build the igt audio test without gsl available.
meson: Add some compiler flags to reduce warnings.
tests/kms_plane: Appease gcc -Wempty-body
lib/ioctl_wrappers: make the valgrind wrapper always emit a statement:w
meson: basic build system support
assembler/test: Prep work for meson
demos: remove
lib/uwildmat: Use include paths
tests/igt_command_line.sh: Allow testing individual tests
lib: clean up header includes
lib: prefix frame_dump_path
build: remove _GNU_SOURCE from source files
build: use HAVE_LIBGEN_H consistently
build: Nuke #ifdef HAVE_CONFIG_H cargo-cult
build: Define _GNU_SOURCE in Makefile.am
tests/kms_properties: Require atomic for the atomic invalid props test
tests/kms_draw_crc: Skip mmap_wc tests if the platforms doesn't support mmap_wc
lib/kms: Skip rather than fail when a suitable plane can't be found
lib/kms: Fix the connector name strings to match what the kernel uses
Fix compiler warnings about printf() arguments
