Hashcat only detect one GPU card

[neodark]

Hi, I have installed Hashcat on a Ubuntu 20.04. I have installed kernel 5.4 generic and uninstalled kernel 5.8. Installed ROCm from this guide (https://rocmdocs.amd.com/en/latest/Insta...tml#ubuntu) and installed Hashcat from apt

With the command "lspci | grep VGA" it detect 4 cards (I have 5 cards RX580... one is "losed")

Code:

root@administrador-H110-D3A:/home/administrador/Escritorio# lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 610 (rev 04)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (rev e7)
04:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (rev e7)
05:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] (rev e7)

When I try "hashcat -I" I got this

Code:

root@administrador-H110-D3A:/home/administrador/Escritorio# hashcat -I
hashcat (v5.1.0) starting...
