That is called a GPE storm; you should be able to find a message about |
10 |
it in `dmesg`, usually those resolve automatically so I wonder why that |
11 |
is not the case here. Can you look for messages about GPE / interrupt |
12 |
in the `dmesg` output? |
13 |
|
14 |
You might also able to use one or another kernel parameter from |
15 |

in an attempt to fix up the ACPI IRQs, try those that mention ACPI, IRQ |
19 |
and/or interrupt(s) in their name or description. Though; as this is a |
20 |
trial and error approach, a specific message and a better idea of what |
21 |
GPE 8 is might yield a better solution when searching this online. |
22 |
|
23 |
As a second question, to figure out what '8' is; take a look at |
24 |
`cat /proc/interrupts` where the last one or two columns of that line |
25 |
give it a name. Feel free to share both `dmesg` and that output with us. |
