[286235.751085] Timeout waiting for hardware access (CSR_GP_CNTRL 0xffffffff) This usually mean problem to talk to device via PCIe bus. It could be iwlwifi driver/firmware problem , but also pci host driver or FW/HW. Or other hardware there are errors from GPU cards as well. Anyway only Intel can fix that.
WiFi bjorked twice tonight. I ran an upgrade which installed a new kernel and some new wifi firmware. How do we convey the details of these failures to Intel so they can fix the firmware and drivers?
We typically can't do much for the CSR 0xffffffff thing. You can look at https://bugzilla.kernel.org/show_bug.cgi?id=201469
This is happening much more frequently than in the past. In the past it happened every few weeks. Now it can occur multiple times a day and it no longer leaves a bug report in Problem Reporting. Any thoughts on how to manually recover without rebooting. In the past I tried restarting the network which didn't work, the on off function of the wifi doesn't do anything when this happens.
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There are a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 29 kernel bugs. Fedora 29 has now been rebased to 4.20.5-200.fc29. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you experience different issues, please open a new bug report for those.
Created attachment 1524835 [details] 300 lines of journalctl after the WiFi failed.
Created attachment 1524836 [details] A few hundred lines of journalctl with error messages regarding WiFi The first file was fouled up so I obsoleted it with this one.
