Could you try the latest upstream kernel which convert dm-crypt's tasklet to BH workqueue? I suppose the commit fb6ad4aec1d0 ("dm-crypt: Convert from tasklet to BH workqueue") might resolve the issue.

And mantic master-next has disabled tasklets for dm-crypt.

https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/mantic/commit/?h=master-next&id=13104eddc76990dc3e4183cff050c9b6dc5e859e

I suppose hwe-6.5 will sync from mantic later, so please try with the newer kernel.

BTW, could you share how to reproduce the issue? I can try from my side in case above commits doesn't help.
