Live System via USB

[harry.gegic]

Hi guys!
I decided to run Kali Linux live via USB and try it out for the first time.
But as soon as I started, I encountered problem.
I followed all the steps to make bootable USB and that was successful.
But when I try to use Kali Linux it does not work.
At first everything is normal, I select option Live system and it starts to boot up.
After some time (when system begins to start some features - like starting modem manager etc) it says failed instead of OK in two lines.
For example:
...
[ OK ] Started load/save screen backlight brightness of backlight:amdgpu_b10.

[ FAILED ] Failed to start load/save screen backlight brightness of backlight:acpi_video0.
See 'systemct1 status systemd-backlight@backlight:acpi_video0.service' for details.

[ FAILED ] Failed to start load/save screen backlight brightness of backlight:acpi_video1.
See 'systemct1 status systemd-backlight@backlight:acpi_video1.service' for details.
...

After some more of these OK lines it starts to list
"amdgpu: [powerplay] min_core_set_clock not set"
for a million times.
After that, it says
AMD-Vi: Event logged [
IOTLB_INV_TIMEOUT device=05:00.0 address=0x0000000nnnnnnn] /where n are random characters/
AMD-Vi: Completion-Wait loop timed out

And repeats these lines for million more times. That's when I turn my computer off in anger.

Thanks in advance :)

Hi,

add GRUB_CMDLINE_LINUX_DEFAULT="quiet acpi_backlight=vendor" to the kernel arguments in /etc/default/grub and everything should work
