Dear Maintainer,

When Debian starts, it reboots randomly at the moment when the radeon
module is enabled. This occurs 3 times of 4 on normal boot mode and
about 1 time of 3 on maintenance boot mode.

Then the USB mouse does not work on Xorg.
When the boot works fine and modprobe radeon is well enabled, all works
fine.

When I run the BIOS settings page in graphics mode and with the mouse, the BIOS works fine, then if I reboots, all work fine
always.

If I run Linux Mint from a USB key and then I reboots on Debian, all
works fine always.

A compilation of xserver-xorg-video-radeon to backport from 1:19.1.0-2 to the 1:19.1.0-3
release does not fix the issue.

Expected: the system should not reboot when the radeon was enabled.

Note: These bottom logs are done when the system works fine.

Regards.
