However, issue is NOT present for me on kernel version 5.4.0-18-generic (but is present on 5.4.0-21-generic and 5.7.0- as mentioned above). Changing kernel versions with grub has been a temporary solution.
Relevant log files are attached from tests in both kernel versions mentioned above (5.4.0-21 and 5.7.0-). Additional log files can be added upon request, as I am able to repeat this simply by changing kernel versions in grub. |

[ 10.714782] rtw_pci 0000:3a:00.0: failed to read ASPM, ret=-5
Device is unable to scan for networks and error occurs when attempting to turn on/off wifi in settings:
[ 302.451636] rtw_pci 0000:3a:00.0: stop vif 5c:ea:1d:b6:17:11 on port 0
[ 308.820551] rtw_pci 0000:3a:00.0: mac power on failed
[ 308.820554] rtw_pci 0000:3a:00.0: failed to power on mac
However, issue is NOT present for me on kernel version 5.4.0-18-generic (but is present on 5.4.0-21-generic and 5.7.0- as mentioned above). Changing kernel versions with grub has been a temporary solution.
Relevant log files are attached from tests in both kernel versions mentioned above (5.4.0-21 and 5.7.0-). Additional log files can be added upon request, as I am able to repeat this simply by changing kernel versions in grub. |
