Hello Fedora Community,
I’m experiencing a critical issue with my Asus Vivobook Pro N552VW laptop running Fedora 42 KDE. My system only boots when I include the nolapic
parameter in grub. Without nolapic
, after the grub menu, the screen remains black and I cannot even access tty.
While nolapic
allows me to boot, it causes severe lag and very slow performance across the entire system. I understand that nolapic
forces the kernel to use the older PIC mode for interrupt handling, which significantly degrades performance.
Laptop Model:Asus Vivobook Pro N552VW
OS: Fedora 42 KDE
Kernel Version: 6.15.3-200.fc42.x86_64
BIOS/UEFI Version: Version 304 (latest available, confirmed no downgrade possible, very limited options in BIOS setup with no APIC settings)
GRUB Parameters Tested (without nolapic
):
noapic
(also failed to boot)
acpi=strict
(failed to boot)
acpi_osi="Windows 2009"
(failed to boot)
acpi_osi="Windows 2015"
(failed to boot)
acpi_osi="!"
(failed to boot)
pci=noacpi
(failed to boot)
irqpoll
(failed to boot)
acpi=off
and …
I have tested various Linux distributions (both older and newer versions) and none of them would boot even into the live environment without nolapic
. After installation, they also refused to boot without this parameter.
Kernel Log (dmesg | grep -i apic
) while booting with nolapic
:
The repeated message ACPI: Unable to map lapic to logical cpu number
seems to be the core issue. Please help me
