I am trying to install Arch on an Acer E5-573 using a USB flash drive. I get a blank screen after Grub prompt and nothing shows up even if I wait for a long time.
I tried adding "debug loglevel=8 earlyprintk=efi,keep" and saw that the last message it prints is a PCI IRQ message like the following:
"pci 0000:00:14.b1 Can't find IRQ for PCI INT A; probably buggy MP table"
There is no option to reset ESCD or PNP data in the BIOS and I have checked that there is no BIOS upgrade avaiable. The device "0000:00:14:b1" represents the XHCI USB 3.0 controller. I have tried "pci=bios", "pci=biosirq", "pcie_hp=msi" and other options like that to force BIOS IRQ allocation and/or to signal MSI as I have read that this is a MSI PCI allocation issue.
Has anybody seen this and solved it ? Does anybody know if the installation kernel supports MSI/MSI-X ?

Could it be IRQ remap that is causing issues since I am booting from USB ? The machine does not have a CD drive, so I am forced to boot from USB only.

I have tried "noapic", "nolapic" and "nosmp" trying to use the legacy IRQ routing but still the same.

Tried the following with no luck
- acpi=off
- pci=noacpi
- pci=nobios
- pci=off

After a lot of reading and searching and after trying a lot of kernel boot parameters with different distributions, I found that the issue is in the BIOS itself. Hence I downgraded BIOS to a previous version provided by Acer. And I was able to boot installation media and install Arch.
