 |
|
Howdy, gentoo users!
I bought recently Alfa Network AWUS036AXM for cybersecurity pentesting. Wifi works well, but bluetooth is destroying everything (seriously)!
If dongle is connected, I even cannot reboot system, because bluetooth service is stuck.
I have big trouble now!

How I can fix it? I need something extra to download? Or something? I don't have any idea );
So guys, what is wrong? I need to get contact with Alfa network? |

"Oops: general protection fault" is often a hardware RAM error. Test that first over several loops, not just once.
Otherwise there is a possible use-after-free in the kernel removing bluetooth devices. |
