This problem seems to popup on the internet every now and then and it seems to effect only AMD processors. The boot-up time for this old laptop running Manjaro KDE (HP Pavilion g6, AMD A4-4300) from about 2014, is not bad at 30-secs. I have tried several of the fixes with no luck and I’m hoping someone has some good news to share in what they did to fix it.
In my case the error “__Common interrupt: 1.55 no irq handler for vector” shows up at boot, disappears to a blank screen and then reappears before ending at the login screen, if I could get ride of this I could shave off another 5-10 sec on boot-up. Other then this the laptop seems to function well for its age. I had a 4g memory that matched the existing 4g and now have 8g to work with and I also dropped in a SSD 500g with 8g swap.
