Hey, On my Onda v975w tablet[1], using a non-upstreamed Realtek driver[2], I used to have the tablet hang after using Wi-Fi for a couple of minutes. I unfortunately couldn't get any stacktraces of the hang. I suspected Power Management in the SDHCI-ACPI driver to be a problem, as the Wi-Fi chipset hangs off SDIO. Using this horror of a patch: https://gist.github.com/hadess/6ce1b1c5dc8f5468d9dc Wi-Fi becomes stable enough to be used. Is this an SDHCI bug? an ACPI bug? A driver bug? If the machine was a desktop, I probably wouldn't care much about the lack of Power Management, but on a tablet...
