This looks like a BIOS defect. BIOS programmed BAR 0 to [mem 0xfe010000-0xfe010fff], but according to the PCI0 _CRS method, that area is not routed to the PCI bus:
ACPI: PCI Root Bridge [PCI0] (domain 0000 [bus 00-fe]) pci_bus 0000:00: root bus resource [mem 0x000a0000-0x000bffff window] pci_bus 0000:00: root bus resource [mem 0x3f800000-0xbfffffff window] pci 0000:00:1f.5: [8086:34a4] type 00 class 0x0c8000 pci 0000:00:1f.5: reg 0x10: [mem 0xfe010000-0xfe010fff] pci 0000:00:1f.5: can't claim BAR 0 [mem 0xfe010000-0xfe010fff]: no compatible bridge window pci 0000:00:1f.5: BAR 0: no space for [mem size 0x00001000] pci 0000:00:1f.5: BAR 0: trying firmware assignment [mem 0xfe010000-0xfe010fff] pci 0000:00:1f.5: BAR 0: [mem 0xfe010000-0xfe010fff] conflicts with Reserved [mem 0xfc800000-0xfe7fffff] pci 0000:00:1f.5: BAR 0: failed to assign [mem size 0x00001000] Can you check to see whether a BIOS update is available? Can you please attach the contents of /proc/iomem (I think you have to save the contents as root in order to see the values). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1884232 Title: touchpad doesn't work at all on ACER Spin 5 Status in linux package in Ubuntu: Confirmed Bug description: Touchpad is not working at all on ACER Spin 5 SP513-54N.
