Linux can't load ramdisk on jetson-tk1 with CONFIG_EFI=y+CONFIG_ARM_LPAE=y

[r-c-n]

Identified by bisection https://groups.io/g/kernelci-results/message/40196 but the commit found as the culprit is most likely unrelated to this issue.

Non-NFS tests, in other words, tests that require a ramdisk, have been failing on jetson-tk1 with config multi_v7_defconfig+CONFIG_EFI=y+CONFIG_ARM_LPAE=y since around 2022-04-30 (v5.18-rc4-205-g3e71713c9e75)

The same kernel version on the same machine with other configs works fine. The same config with NFS tests works fine. I have no information about the specific jetson-tk1 machine that ran the tests on lab-baylibre, but maybe that's something to inspect further.

@hardboprobot I haven't looked into this issue in much detail but just FYI we have some failures related to ramdisk https://gitlab.collabora.com/kernel/kernelci-regressions-tracker/-/blob/main/configs/logs-string-match.yaml

I have added a string for the same in infrastructure failures.

Old issue. (also we are not tracking kernel test failure/issues through GitHub anymore)
