I get the same error on 6.5.7-zen and on 6.5.9-zen (but seqno is 23) but it works for hour or maybe two and then hosts runs out of memory. Memory leak occurs somewhere.

我在 6.5.7-zen 和 6.5.9-zen 上遇到相同的错误（但 seqno 是 23），但它可以工作一个小时或两个小时，然后主机内存不足。 某处发生内存泄漏。

Me too, the kernel memory overflowed, not the process

ok so I figured it out, I found this commit that solved TLB invalidation kernel error https://github.com/intel/linux-intel-lts/commit/c75552e4fc1b556c4d33ec20ec1e5c99f666068e
