Run ChatRWKV on MBP(intel CPU)+eGPU[rx6800 16G], returna a very big number -9223372036854775808, looks like overflow
Labels: triaged, module: mps

### 🐛 Describe the bug

Run [ChatRWKV](https://github.com/BlinkDL/ChatRWKV) using 'mps', returna a very big number, looks like overflow.

MBP(intel CPU, not M1/M2), with eGPU[rx6800 16G]
pytorch==2.0.0

It can  load model, but when calculate the 1st token, it gets a very big number `-9223372036854775808` and return error.

error log:

```
Bob: hi

I tried to rollback to the previous version of pytorch(1.12.1/1.13.1), it will send a warning msg and fallback to cpu, but it can  return a correct number:

```
