hi guys, maybe my information helps a bit (at least a hope) my PC is a 1700x with the gaming aorus 5 from gigabyte (GA-AX370-Gaming K5), got 32 GB RAM but i dont think that it has much to do with all the problems metioned above.
i got all those errors, and i can only use my computer with my new graphic card (all cores and stuff) using the kernel "4.7.8-040708-generic"... there is no other kernel that works with that graphic card (rx 460) for that reason im using it... and other newer kernel just failed... i have like 24 newer kernels installed... all of em come with this IRQ erros and stuff... but i did some check, i changed the default grub, i wrote (if am not mistaken) acpi=off noacpi or something like that (sorry i cant remember it right now, im not at my pc) and i got this irq 7 issue even with the kernel im using... so i had to changed the default grub... and i could work again with the 4.7.8... kernel i hope this information can help you somehow. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1671360 Title: System doesn't boot properly on Gigabyte AM4 motherboards (AMD Ryzen) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1671360/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
