Perhaps, there should be a category for tentative errors and/or 
tentative warnings (i.e., with an unknown (or yet unknown) severity in 
practice).  E.g., dereferencing a zero pointer, or division by zero, or 
garbled screen output, or the inability to read '/' as the root user, 
etc. are almost always errors (except when you test error-handling 
routes themselves; then a division by zero is not a bug but a must).  If 
you say that it is unknown how severe a message such as “ACPI Warning: 
SystemIO range … conflicts with OpRegion … . lpc_ich: Resource 
conflict(s) found affecting gpio_ich” really is, it should not be a 
warning (especially, it should not warn the reader) but be a tentative 
warning (i.e., it might warn the reader in the future or under 
particular circumstances).  The (new?) colors of the tentative errors 
and warnings should be clearly stated in the manpages of journalctl.

If there is still an actual problem on this machine (not just warning
messages), please open *1* bug report that describes the actual problem
and the log messages.


If under *actual* you mean *user-disturbing* (“error, flaw or fault in 
the design, development, or operation of computer software that causes 
it to produce an incorrect or unexpected result, or to behave in 
unintended ways”, a definition from Wikipedia), I've got none for the 
kernel because the kernel is not visible (nor should it be visible) to 
users directly.  The only (sometimes reproducible) full lock-up (SysRq 
doesn't seem to work) I saw myself, which might concern the kernel, 
happened when epiphany-browser loads Google maps directly or embedded 
into a different Web site; I plan to submit a bug report.


As for other high-level problems which are already posted, there are at 
least two (and more are likely to come).


One of them, already resolved recently (though the root cause is still 
unknown, the intermediate problem is gone) is #1041014.  If I had to 
state the *actual* problem there, it would have been „the machine 
doesn't boot properly, the screen is black, the keyboard doesn't seem to 
respond“; such a description would've probably been considered *actual* 
but pretty useless to the maintainers.  Even if it would have been 
useful to you, then only in the sense that a failure to start a 
graphical user interface should not prevent text logins from visibly 
showing up on Ctrl + Alt + F1 … Ctrl + Alt + F6 and that error codes 
(instead of "ERRNO" and "exit-code") from failed spawns by systemd 
should be printed.


As another big problem on another machine, cf. #1040497.  A next step in 
debugging this could be looking at how /run/gdm3/custom.conf is created, 
whether the logic in /lib/udev/rules.d/61-gdm.rules is correct, and 
whether using X.Org (in Debian 12) instead of Wayland (in Debian 11) is 
really justified on the particular machine 
(https://gitlab.gnome.org/GNOME/gdm/-/merge_requests/171#note_1403697 
doesn't apply in my use case because the onboard graphics chip is 
usually not connected to a monitor in my setup, except if the monitor 
connected to the PCIe NVIDIA card happens to fail, which has not yet 
happened).  If this issue involves the kernel at all, then probably the 
nouveau driver.  The details of this issue are beyond my level of 
expertise, so I'm unsure how much I can really do myself.


Gratefully,
Alma

This is a rather naive understanding of how logging is done in
practice.  The reality is that developers often don't know (and maybe
can't know) just how severe an odd condition may be in practice.

I agree with Diederik's closing these bug reports.  We as kernel
maintainers have limited time and resources for investigating bugs, and
we are certainly not able to provide individual support for users and
administrators.  Investigating warning messages one by one is not a
priority at all.

If there is still an actual problem on this machine (not just warning
messages), please open *1* bug report that describes the actual problem
and the log messages.

Ben.

That's wrong.
Before I posted some (not all) of the bug reports, the Dell laptop 
stopped booting properly rather early; the root cause is still unknown 
(though an intermediate cause is finally resolved now, the bug report is 
already closed).  It took me a bit to get a working console, a mouse and 
network going so as to simply be able to start debugging.  Some other 
machines I manage had (and still have) other, less severe symptoms, 
e.g., Wayland and programs depending on Wayland (e.g., “foot”) failing 
to start after Debian upgrade.


If your computer doesn't boot properly, you go one by one through every 
suspicious message you find. The fact that some messages are shown as 
warnings and others as errors is clearly meant to warn whoever reads 
them (i.e., the admin) and make him/her concerned.  By the definition of 
the terms “warning” and “error”!  If these messages shouldn't make the 
admin concerned, well, then the journalctl shouldn't show these messages 
as warnings (AFAIK, yellow) and errors (red according to `man 
journalctl`).  Please don't try to unload on me because of this mess; 
I'm just an admin, and not even a developer.


Therefore, please restore the bug reports you closed.
