Dear Madam or Sir, Linux logs several warnings on the Dell Precision 3540. ``` [ 0.095173] x86/cpu: SGX disabled by BIOS. [ 0.095455] MMIO Stale Data CPU bug present and SMT on, data leak possible. See https://www.kernel.org/doc/html/latest/admin-guide/hw-vuln/processor_mmio_stale_data.html for more details. [ 0.095455] #5 #6 #7 [ 0.160862] ENERGY_PERF_BIAS: Set to 'normal', was 'performance' [ 0.925854] hpet_acpi_add: no address or irqs in _CRS [ 0.935985] i8042: Warning: Keylock active [ 1.154956] wmi_bus wmi_bus-PNP0C14:03: WQBC data block query control method not found [ 2.281890] device-mapper: core: CONFIG_IMA_DISABLE_HTABLE is disabled. Duplicate IMA measurements will not be recorded in the IMA log. [ 113.577465] systemd[1]: /lib/systemd/system/rstudio-server.service:11: Unit uses KillMode=none. This is unsafe, as it disables systemd's process lifecycle management for the service. Please update the service to use a safer KillMode=, such as 'mixed' or 'control-group'. Support for KillMode=none is deprecated and will eventually be removed.

Could Canonical/Ubuntu please make it a requirement for certification, that `dmesg --level=crit,alert,err,warn` is empty.
