Kernel BUG with AMDGPU when resuming from system suspend
Brief summary of the problem:
I have a laptop (HP 15s-eq2147ng) which comes with a AMD GPU named Lucienne. In the month that I have been using it I have observed that sometimes the display is completely frozen after resuming a system suspend. Network still works so I can perform a clean reboot via ssh.
The journal contains traces of kernel bugs that are always correlated with a resuming from suspend (although not completely sure whether fully correlated with the freezes). The likelihood of the kernel bug happening is not very large: until now 3 kernel bugs after 71 suspends.
The OS is a stock Debian Bullseye installation with the following kernel:
Linux hostname 5.10.0-8-amd64 #1 SMP Debian 5.10.46-5 (2021-09-23) x86_64 GNU/Linux
I attach the kernel bug trace as shown in the syslog, the output of lspci, lshw and acpidump. I also attach the output of journalctl | grep amdgpu in case it is useful.
