Issue: CUDA: Illegal memory access in `torch.linalg.solve()`
Labels: high priority,module: cuda,triaged,module: linear algebra

### 🐛 Describe the bug

Hi,

My program randomly terminates both during training and validation and I strongly suspect that it is due to torch.linalg.solve(), although I have not been able to reproduce the bug in a simple script with a for loop.
Here's a snippet for convenience, (ignore the edge case where the rows of x would be linearly dependent, as this does not happens in the actual function):
```python
import torch

device = torch.device("cuda")

x = torch.randn(64, 81, 9, 5, device=device)
y = torch.randn(64, 81, 9, 1, device=device)

A = x.transpose(-1, -2) @ x
B = x.transpose(-1, -2) @ y
b = torch.linalg.solve(A, B)
```

The following error is consistently returned after enough epochs:
```

```

This happened both on single GPU and multi GPU (DDP) settings.
Am I better off using something like this even though this is not recommended?

```python
b = A.inverse() @ B
```

If you have got any pointers on what I should be doing instead :)

Best regards,
