Dear Andrew folks, dear Linux folks,


On a four socket Dell PowerEdge R815 with AMD Opterons 6276, Linux 5.4.14
hit the kernel bug below. We were *not* able to reproduce it yet.

We haven’t seen this before with Linux versions up to 4.19.57, but
also only started to use this system as a cluster node now. Before
it was used interactively.

Could this be a regression from 4.19.x to 5.4?


Kind regards,
