Package: linux-image-6.1.0-10-amd64
Version: 6.1.37-1
In the depths of my journal I discover the following two warnings
(“ata2.00: supports DRM functions and may not be fully accessible” are
marked orange):
$ grep -i ata2 -C 1 /tmp/j.log

In plain English, what do the two warnings “ata2.00: supports DRM
functions and may not be fully accessible” tell us? What does DRM stand
for in this context? There are also rejected ACPI commands and ACPI-cmd
errors marked as non-errors (i.e., in usual, maintext gray-white), e.g.,
“ACPI cmd 00/00:00:00:00:00:a0(NOP) rejected by device (Stat=0x51
Err=0x04)”. Is there a configuration issue; do we have to worry about
these warnings and errors? The machine is a Dell Mobile Precision
M6700; ata2 most likely refers to an internal 2.5-inch SATA SSD. The
machine has problems later during boot, so it's important for us to know
the extent and the implications of the warnings and errors here.
Gratefully,
AlMa
