I can confirm that the AX200 works OK when plugged in a x1 PCIe slot, and does NOT work in a x16 slot. In the later case it generates the before-mentioned
"NMI_INTERRUPT_UMAC_FATAL" followed in the logs by iwlwifi 0000:01:00.0: Failed to start RT ucode: -110 iwlwifi 0000:01:00.0: Failed to run INIT ucode: -110 My setup is * Gigabyte Z97M-DS3H motherboard * Fenvi FV-AX200 PCIe x1 adapter card with an Intel AX200NGW NGFF M.2 card * CentOS 7 (stock 3.10.0-1127.19.1.el7 and mainline 5.8.7 kernels tested) I want to point out that the adapter card works fine in the x16 slot when used with another WiFi module (DELL's DW1820), so the problem clearly lies with the AX200 not negotiating its PCIe configuration with the motherboard/chipset. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848831 Title: Intel WiFi AX200 [8086:08b1] subsystem [8086:4070] firmware loading error resulting in no wifi To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntux/+bug/1848831/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
