Created attachment 276005 [details] full dmesg My dmesg show's the error: [ 3.971632] ioremap error for 0x3f781000-0x3f782000, requested 0x2, got 0x0 ... after a fresh reboot. The error is printet in between WMI and UVC camera modules are loaded, but my laptop seem to operate normal despite the error. The other errors in the attached dmesg log are reported in other bugs. I'm running up-to-date Debian buster/sid on a Dell XPS 9370 laptop.
the bug seems to be related to: https://lkml.org/lkml/2018/5/16/665 as Paul Menzel wrote: >>>> The ioremap error is what causes ucsi_acpi to fail the probe call (-12 >>>> is "out of memory".)
not using the laptop anymore. error did not seem to break my everyday workflow.
It seems to be from ucsi_acpi: [ 3.971632] ioremap error for 0x3f781000-0x3f782000, requested 0x2, got 0x0 [ 3.971670] ucsi_acpi: probe of USBC000:00 failed with error -12 The Dell Precision 3540 has the same issue, and I contacted the developers [1].

Hi Paul, I've tested your patch in the above thread and I confirm that the message disappears on 5.18.3 + your patch.
