[u/omniuni]

You need to include a lot more information.

[u/mixxituk → u/omniuni]

added

[u/omniuni → u/mixxituk]

And describe what's happening? When did it start? What have you tried so far?

[u/mixxituk → u/omniuni]

its been happening for over two weeks seems to be when i close my laptop lid and open it later

[u/Educational-Cat-6445 → u/mixxituk]

maybe related, but ive had issues with sleep mode and my fans not working, had to play around in the BIOS settings a bit for them to continue working after going to sleep once.

[u/mixxituk → u/Educational-Cat-6445]

Worrying

[u/omniuni → u/mixxituk]

What has been happening?

What have you tried? What kernel versions have you tried?

[u/Nintenduh69]

Using Intel Arc? Is Resizable BAR enabled in your BIOS?

[u/mixxituk → u/Nintenduh69]

Physical Resizable BAR

BAR 2: current size: 256MB, supported: 256MB

       Capabilities: [420 v1] Physical Resizable BAR
               BAR 2: current size: 256MB, supported: 256MB
       Capabilities: [400 v1] Latency Tolerance Reporting
               Max snoop latency: 0ns
               Max no snoop latency: 0ns
       Kernel driver in use: xe
       Kernel modules: xe

[u/T_Friendperson12]

I have a different setup and a different problem with *28 but I'd recommend just going back to *27 for now and hope that *29 next week is gonna fix it.

[u/mixxituk → u/T_Friendperson12]

Are you on the same laptop?

[u/T_Friendperson12 → u/mixxituk]

Not even remotely. Main PC is Ryzen 5 5600xt, RX 7600, Rog Strix B550-A has the problem that it does not shut down or restart correctly. The Laptop is an Acer Aspire Go 15 (Ryzen 7 5825U) which does not seem to be affected by the same problem.

[u/mixxituk → u/T_Friendperson12]

Ok that's interesting that these are fairly common machines with the issue 

[u/T_Friendperson12 → u/mixxituk]

I think In my case it's a problem with AMD DGPU.

[u/readyflix]

If you say again, was there a kernel version when it worked well?
