Thanks. So I installed 18 LTS again. A major PITA, but I used 18 LTS on this laptop for 2 full years without a problem. Always fully upgraded, so with all the standard permutations of kernel, modules and firmware, on lots of different wifi networks. There was never a single issue. Nor under 16.10 or 20 LTS for the first year.
This time it crashed within 2 hours. I take this as final confirmation that this bug is not all it seems. There is clearly an arbitrary hardware component. The laptop is on its last legs. It's on its second power block, one USB port is gone. Apparently this is way the wifi chip goes out. Thanks for the ideas and feedback. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1882968 Title: ath10k_pci failed to wake target for write32 Status in linux package in Ubuntu: Expired Bug description: Wifi card stopped working.
