Kernel 7.0.14-26 makes zfs replication hang on receive

I have updated to kernel 7.0.14-26 a few days ago:
pve-manager/9.2.24/66bc407c6d90a67a (running kernel: 7.0.14-26-pve)

Ever since, zfs receive of encrypted datasets (with syncoid) occasionally make the entire zfs pool hang.

Process info and stack trace shows that even pvestatd is hung on waiting for zfs in D state. See the logs below.

This prevents soft reboots, as the reboot itself is being blocked on zfs as well as renders the web UI largely useless, likely due to pvestatd being stuck.

Is this a known issue? I see in the changelog that there were very specific changes in the new kernel affecting encrypted zfs receive, something might have gone off the rails there:
https://github.com/proxmox/pve-kernel/blob/master/debian/changelog
Should I roll back the kernel version?

Could you please share the kernel logs from when the issue occurred using the following command so we can investigate further?

Code: 
journalctl -k -b -1
 
Is the log very long?

If possible, could you share the relevant log entries directly in your reply, formatted as a code block?

Please redact any sensitive information, such as IP addresses or hostnames, before posting.

It is mostly the boot log, then the first reports of the stuck processes:

Thank you for taking a look that quick.
I can confirm on my side that:
- The issue happens when there is read load on a zfs pool that is being received.
- After pinning 7.0.14-25-pve the issue resolved.
