Hello,

This looks like a bitflip, the address used should probably be 0xffffffff9286f8b0.

Is this problem reproducible for you? Does it always happen on the same
address? Is that a regression (i.e. earlier kernels work fine)?

Can you run a memtest on your machine please? (Install memtest86+ and
boot into it.)

Best regards
Uwe
