firefox, not fio. It's a problem with libpci: #3 0x0000007fb5074b20 pci_generic_error (libpci.so.3 + 0x2b20) #4 0x0000007fb507630c pci_init (libpci.so.3 + 0x430c) Firefox uses that to detect VGA adapters. I see it's aarch64 - may that be a factor here? Michal, I see you did some work on libpci, do you have any idea how to handle that? Thanks. The device was a pinephone, which ode snot even have the bus interface to query the pci devices. The patch needs to check that the pci interface iteself exists, before querying the devices. > Firefox uses that to detect VGA adapters. I see it's aarch64 - may that be a

That won't work for a lot of ARM devices because most display GPUs and related HW aren't attached by pci so lspci or associated API won't return a display adapter.
If there is no pci bus on that device it won't work. You should probably check it in advance if it exists or not. If you can't do that, you can replace pci_access->error method between pci_alloc(...) and pci_init(...) to set some global flag, test it if initialization failed and handle it the way you need. > Firefox uses that to detect VGA adapters.

By "detect VGA adapters" do you mean the model of the GPU to work out some capability? What functionality is this used for?
