Hi, I'm trying to track down the root cause of https://bugzilla.kernel.org/show_bug.cgi?id=194141 and I'm a bit stuck. Currently my understanding is: 1. early on boot acpi_register_gsi_ioapic(NULL, gsi=18, ...) is called for smo8800 driver 2. later i801_probe() calls pcim_enable_device(), which eventually calls acpi_register_gsi_ioapic(i801_smbus, gsi=18, ...), which fails; failure then propagates back to probe. (if I insert code to fail on step 1, step 2 succeeds, and driver works) Now, to me it's understandable that registering IRQ fails, since smo8800 doesn't share it, but should that mean pcim_register_device fails too? -- Domen
