I just finished configuring F25 on a new Dell precision 7520 (essentially same as 7510) with Samsung's PM961 1TB PCIe M.2 SSD "disk". Wonderously fast! Boots in like 2 seconds. KDE comes up in 5. HOWEVER: In the boot messages (/var/log/messages) I see these lines: kernel: Intel(R) Wireless WiFi driver for Linux ... kernel: iwlwifi 0000:02:00.0: Direct firmware load for iwlwifi-8265-28.ucode failed with error -2 ... kernel: iwlwifi 0000:02:00.0: capa flags index 3 larger than supported by driver kernel: iwlwifi 0000:02:00.0: loaded firmware version 27.455470.0 op_mode iwlmvm ... kernel: iwlwifi 0000:02:00.0: Detected Intel(R) Dual Band Wireless AC 8265, REV=0x230 kernel: iwlwifi 0000:02:00.0: L1 Enabled - LTR Enabled kernel: iwlwifi 0000:02:00.0: L1 Enabled - LTR Enabled kernel: iwlwifi 0000:02:00.0 wlp2s0: renamed from wlan0 ... There's a few more iwlwifi related messages when NetworkManager comes up. No errors. Things appear to work fine. Then sometime later (could be minutes or hours, in the middle of a large download, the transfer rate goes to nearly 0 and a boatload of messages like this dump into /var/log/messages: kernel: iwlwifi 0000:02:00.0: Microcode SW error detected. Restarting 0x82000000. kernel: iwlwifi 0000:02:00.0: CSR values: kernel: iwlwifi 0000:02:00.0: (2nd byte of CSR_INT_COALESCING is CSR_INT_PERIODIC_REG) kernel: iwlwifi 0000:02:00.0: CSR_HW_IF_CONFIG_REG: 0X00489000 kernel: iwlwifi 0000:02:00.0: CSR_INT_COALESCING: 0X00000040 kernel: iwlwifi 0000:02:00.0: CSR_INT: 0X00000000 kernel: iwlwifi 0000:02:00.0: CSR_INT_MASK: 0X00000000 kernel: iwlwifi 0000:02:00.0: CSR_FH_INT_STATUS: 0X00000000 kernel: iwlwifi 0000:02:00.0: CSR_GPIO_IN: 0X00000010 kernel: iwlwifi 0000:02:00.0: CSR_RESET: 0X00000000 ... After this, the "Microcode SW ..." message appear every few seconds or minutes with the boatload of CSR values. I have to reboot to get things right. Then it (intermittently) happens again on some future download. Is this a hardware bug that I'll be stuck with forever? If so, I have only a short time to return the Dell before "it's mine". Your help will be greatly appreciated! By the way: "lspci | fgrep -i wireless" returns 02:00.0 Network controller: Intel Corporation Wireless 8265 / 8275 (rev 78) -Sherman _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx
