I am using a pico-itx computer 'aaeon pico-tgu4' with only ubuntu 20.04 system installed. The system works well when nothing added. When i add a mini-pcie network card AX210 or AC8625 then booting the system, i get some errors:
[ 0.181251] ACPI BIOS Error (bug): Could not resolve symbol [\_SB.PC00.TXHC.RHUB.SS01], AE_NOT_FOUND (20201113/dswload2-162)

[ 0.181275] ACPI Error: AE_NOT_FOUND, During name lookup/catalog (20201113/psobject-220)
which makes me unable to boot the system.
Then I add the param acpi=off, error still but system boot successfully with only 1 cpu core (I need 8 to have good performence)!
After that I try the param 'pci=noacpi', error still but system boot successfully with all cpu core, but I find that all serial device that need pci cannot work (i cannot write or read the /dev/ttyS*).
I am a NOOB in ubuntu, could somebody help me to solve this problem? thx :)
