HP EliteBook 2740p
Intel Core i5-540m
8GB DDR3
Crash/hang shortly after booting into Budgie, consistent with 5.4.x kernels and in opposition to 5.10.x kernels, which would usually run for extended periods of time before hanging.
4.14.x LTS works as expected still.
This kernel message seems salient:
i915 [drm] ERROR Failed to wait for idle; VT'd may hang.

Everything has been working very well on my end, the only slight change i've notice is sporadic extremly breif screen tearing / flickering. It's almost unnoticeable because its so quick, and it doesn't occur too often, just the only thing i've personally noticed. Other wise all fine.
Running on a 3 year old HP spectre x360 and the KDE desktop
I have hp15-bw011nt and I have RTL8723DE wifi card so I need at least the kernel of 5.10.12.
Now it is upgraded to 5.11, it seems no problem at all.

I hate to do this, but I can no longer edit my prior post.
This discussion highlighted the kernel command to turn off the intel_iommu for the igfx.

I wrote it out using the discussion here:

On kernel 5.11.6-174.current for over 9hr now under normal to heavy load, and no random hangs/freezes. Without this option, I would typically hang/freeze within a minute of boot/login of Solus on the 5.11.x kernels. Suspend/reusme, sleep/wake, shutdown/reboot, and hibernate/restore all work, which is in stark contrast to other 5.11.x kernels.
Other improvements from 4.14.x LTS like way faster WiFi performance and cooler running CPU remain, even with that kernel config option.
Failure here : amdgpu not initializing.
Pastebin :
My bootloader is OpenCore (PC faked to Mac) if that matters..
Thks for the review!
Previous message deals with Gnome on fortitude 4.2
I have another install (just before 4.2) with KDE : this one boots with 4.11 without problem.
So, it's not my rig.

Hi @JoshStrobl Sorry for missing this thread in the first instance so re-posted here as you suggested.
I just installed Budgie 4.2 on my Mothers HP Notebook - 15-db0000na.
After some fiddling around with the Bios settings I finally got the Live USB to boot.
I installed Solus replacing the hopeless Windows 10.
I rebooted and all was working great! 
Solus updated and installed the new v5.11.xxx Kernel and some other bits n bobs.
After I was done I turned off the laptop and thought Job done.
When I turned on the Laptop this morning the screen backlight came on but nothing else happened.
Pressing the space bar during the boot process presented me with options to boot the old kernel so I did and this time it booted up fine.
I have wiped and reinstalled about three times.
I swapped out the Hard drive incase it was failing as windows 10 was super slow but that made no difference
I have done all the package updates and checked for Incomplete ones.
I have done all the ctl-boot-manager stuff too but the v5.11.xx Kernel simply refuses to boot this Laptop. 
inxi -F is here https://del.dog/kahidimagn
dmesg using the com.solus-project.current.5.10.12-171 Kernel is here https://del.dog/tanapakinu
I have this kernel set to default for now so no issues so far booting and using the Laptop.
@JoshStrobl The update to 5.11.9-176 fixed my corrupted display issue. High five.
Upgraded from 4.2 iso right after fresh install and the best thing every that RTL8723DE driver is now included 
, no issues so far.
Great work guys 
Still no luck with latest update under gnome :
But the Solus install with kde boots with 5.11.9..
And the gnome install works great with 5.10.
5.11.9-176, kernel update fixed boot hangs for AMD A9-Raedon Graphics. Kernel 5.11.6.XXX caused severe problem with my laptop kept hanging during boot. Alternate way used clr-boot-manager to set kernel to old 5.10.X.XXX. Thanks with new update on kernel.
Latest kernel failed.
Compared 5.10 and 5.11 drm initialization processes and notice that 5.11 was using a different version of displaycore.
added amdgpu.dc=0 to cmdline and voila!
gnome booting with 5.11-current.
Mascaret What GPU?
On-topic, no issues with RX 580 here.
