I've reproduced Janne's panic with ubench twice.  Both show similar
outputs from the panic.  Panic #3 is proving more elusive: I'm running
ubench for the fourth time in a row now waiting for crash #3.

This is the 5.2 kernel with SMBFS and such turned on.  These are the
first two panic's I've seen in two months.

panic: vm_page_alloc: free/cache page 0xffffff01faf5db50 was dirty
cpuid = 1;
