SD card timeout issues in RPi4

Affected images versions

• not relevant (explain why)
• see the table below (list the build id and the apt or ostree deployment of the tested images in the appropriate cells)

Type	Arch	v2021	v2022	v2023pre
minimal/fixedfunction	amd64
minimal/fixedfunction	armhf
minimal/fixedfunction	arm64			x
target/hmi	amd64
target/hmi	armhf
target/hmi	arm64
basesdk	amd64
sdk	amd64
nfs	amd64
nfs	armhf
nfs	arm64
lxc	amd64
lxc	armhf
lxc	arm64
image-builder
package-source-builder

To find the build id and the variant type you can:

• derive it from the image name
  • for instance, with the apertis_ostree_v2022pre-fixedfunction-amd64-uefi_20211031.0425.img.gz image the build id is 20211031.0425, the variant is fixedfunction the deployment type is ostree
• obtain it from /etc/os-release using the BUILD_ID and VARIANT_ID keys

Steps to reproduce

Expected result

The test should pass

Actual result

Test is not able to complete due to timeout:
