Example of failed prime95 session

My old Intel nehalem based system is not able to run prime95 anymore starting with commit 87d0e5be0fac322f4415128def9f16a71a267a40. See attachment for example of failed prime95 session.
On commit bf5d00470787067ff27593c6a097b5eb6e01168e this system is able to run prime95 for hours without error before I stop it.
My ivy bridge based laptop seems to be unaffected.

Turns out that this was a openzfs bug (https://github.com/openzfs/zfs/pull/13236). Sorry for the noise.
