Same problem here. Without init_on_alloc=0 suspend to RAM is not working (system freezes).
With init_on_alloc=0 suspend to RAM is working, but waking up sometimes is not working.

As reported here[1], it is reported that you can use the following two
kernel paramters to workaround the issue (adding "init_on_free=0" to
the previously reported "init_on_alloc=0"):

init_on_alloc=0 init_on_free=0

If it can be usefull, I was able to replicate the issue affects Linux
kernel version 5.14 and the actual 5.15 in sid/unstable. Therefore, both
the kernel versions seem to be affected together with 5.10 version.
