I have tested your patches against few kernel versions without reproducing the issue.

I didn't touch to CONFIG_VMAP_STACK though.
The main difference from my crash report is my test environment which was a downstream one.
So it seems related to ST downstream kernel version based on a v6.6.48. Even though the backtrace was talking about unwinding and kasan.
I will continue to investigate on my side in the next weeks but I don't want to block the patch integration process if I was.
I think we can assume that the patches we have queued in Russells patch tracker at least don't make things worse, so let's merge those and then see if there is more fallout we need to dig into as you test.
Thanks Clement!
