I have a mid-2010 iMac (iMac 11,2), with a Mobility Radeon HD 4670, running
Linux Mint 21.1 Xfce Edition, and it has several issues. I've decided to report
the issue here since it seems to be a kernel bug, and since Mint is based on
Ubuntu where its kernels are built, I thought it'd be wise to report here and
escalating to the LKML if necessary. Firstly, its display turns off when it
boots, unless an external display is connected, in which case both displays
work fine. But the backlight can't be controlled by typical programs
(brightness buttons don't work, and xbacklight says 'No outputs have backlight
property') apart from light (https://github.com/haikarainen/light); but that
only works on kernels 5.15.*, not on 6.3.4, on that kernel only the brightness
value changes, but to no effect. Upon bootup, I can see:
uhci_hcd 0000:00:1a.0: Found HC with no IRQ. Check BIOS/PCI 0000:00:1a.0 setup!
uhci_hcd 0000:00:1a.0: init 0000:00:1a.0 fail, -19
uhci_hcd 0000:00:1d.0: Found HC with no IRQ. Check BIOS/PCI 0000:00:1d.0 setup!
uhci_hcd 0000:00:1d.0: init 0000:00:1d.0 fail, -19
at the top of the screen for a few seconds before the Mint splash screen
takes over.
The device's internal display turns off upon wake up from suspend,
giving the following output in dmesg:

The cursor also seems to dissapear after some use, although it remains
functional. What I mean is the "icon" for it doesn't exist anymore, but
moving the mouse around I can see some buttons display their shadows
indicating that the mouse is above them and clicking the buttons works.
Using SWcursor in Xorg "fixes" this issue, but the mouse becomes
flickery and this is obviously a sub-optimal hack.
I can consistently get the system to freeze by opening some specific websites
in Firefox: any video on yewtu.be or youtube.com, amazon.co.uk and
discord.com/app after some usage. It seems the thing they have in common is
some sort of video playback, although autoplay is off, but the system freezes
immediately once it finishes (and sometimes before it even does finish) loading
the website. What's even more strange is that local video works, using mpv for
example, and Blink based apps don't seem to suffer as much. Almost no freezes
happen with Chromium and Freetube (which is Blink-based afaik), but the system
does occasionaly freeze for several seconds, and then the internal display
turns off, but is still "functional" in the sense that windows are still
rendered on it and I can drag windows back and forth from it, but it is
completely black, when using these apps. This happens incosistently and
randomly, though. I have some errors for this experience after using Discord
for a few minutes on chromium:

Lastly, on only one bootup, I noticed semi-random artifacts in text and
icons that seemed to go away with a logout/login. Identical artifacts
seemed to appear in the exact same place on the exact same characters
wherever those characters appeared. I've attached a few photos showing
this. I've also noticed this in dmesg when the artifacts appeared:
kauditd_printk_skb: 16 callbacks suppressed
Not sure if it is related or not, but I've included this info just in
case.
All the logs and bugs have been observed on linux 5.15.0-72, but I've
also installed 6.3.4-060304 from the Ubuntu mainline kernel PPA recently
and observe similar/same bugs, and since this is quite an old code path,
I doubt it has changed much, but I can try and recreate them again with
the new kernel version if needed.
