LOS 23.2 ramoops kernel panic on kernel 4.19 sm6225 motorola devices

Hello, I'm posting this to see if there are more people getting this problem where devices like capri (the one I'm using) or guam may suddenly hit ramoops after some time and kernel panics, this behaviour maybe related to MGLRU especially the lru_gen_look_around() function being present in the ramoops log, this also could be a deadlock in queued_spin_lock_slowpath inside shrink_page_list and page_vma_mapped_walk path.

The device becomes sluggish after the active(anon) memory drops to 0 which makes LMK aggressive, killing as many processes it can, the inactive(anon) memory becomes inflated as time passes and then the kernel panic.

Despite the issue being reported many times on the bug tracker a little attention has been brought by maintainers and the bug remains, I'm not scolding any dev but what I'm asking for is a bit of time and attention to this egregious bug ofc take your times what I need is assurance that this will be worked with at least.
