Bug Description
Hardware: Acer CB3-131 Chromebook (GNAWTY) running Ubuntu Mate natively (BIOS enabled by SeaBIOS firmware from scripts here:https:/
01:00.0 Network controller: Intel Corporation Wireless 7260 (rev bb)
Software: Ubuntu Mate 17.04, upgraded from 16.10. Currently, everything (kernel, firmware, etc.) is stock. Issue has persisted across multiple installations.
Bug: Wifi/Bluetooth crashes and refuses to come back up, even after multiple reboots. Issue persists across distros (Arch, Ubuntu, etc.)
When the wireless (Bluetooth and WiFi) works, it works flawlessly. However, upon boot, it is not uncommon for the wireless to stop working within two minutes of login time. Curiously, the GUI usually still shows being "connected", though trying to change anything with the wifi shows otherwise. Other times, upon system resume when wireless was previously working, the GUI will show "device not ready" and refuse to continue. Dmesg shows the following:
[ 423.814823] Bluetooth: hci0 command 0x1403 tx timeout
[ 424.172973] iwlwifi 0000:01:00.0: Failed to wake NIC for hcmd
[ 424.173062] iwlwifi 0000:01:00.0: Error sending SCAN_OFFLOAD_
[ 424.173067] iwlwifi 0000:01:00.0: Scan failed! ret -5
[ 425.194487] iwlwifi 0000:01:00.0: Failed to wake NIC for hcmd
[ 425.194589] iwlwifi 0000:01:00.0: Error sending SCAN_OFFLOAD_
[ 425.194593] iwlwifi 0000:01:00.0: Scan failed! ret -5
Solution: Rebooting doesn't fix the problem. Perhaps a different firmware version will work better? Configuration settings? etc.? Unknown.
Thanks ahead of time for the help. Let me know if there's anything you need/commands I should run/solutions I can attempt.
