Hi Developers, I am experiencing issues with rtl8192 drivers on an MSI X370 laptop with Ubuntu 11.10 AMD64 : The driver works fine upon a fresh boot (not exactly, see explanations below), but not after toggling the hard rfkill switch. I think that might be a driver issue, and I am willing to provide more information if that would be helpful. Here are what I have gathered (reproducible every time): 1. Boot. The kernel is not detecting the device if hard rfkill is enabled before boot (this seems to be a kernel bug, but can be workarounded by pci rescan), otherwise the device is detected and driver is loaded. The driver works either way the first time it is loaded. 2. Enable hard rfkill. I found 'udevadm monitor' output nothing regarding this action, and /sys/class/rfkill/rfkill*/hard reads constant "0". 3. Disable hard rfkill. From now on the driver no longer works until next boot. I tried rmmod/modprobe with no success I will try the tarball from Realtek to see if there is any difference. relevant lspci output: 03:00.0 Network controller: Realtek Semiconductor Co., Ltd.
