 Dear Marius,
 
 looking a bit more closely, I also agree that the size parameter is
 incorrect. However, it should not make a difference on sparc64, since
 sizeof(u_int64_t *) = 8 = sizeof(u_int64_t).
 
 I started a new kernel build with the official fix in PR 140797 right
 after I wrote my last e-mail, and with any luck, it should finish in an
 hour or so. I'll let you know if I can reproduce the panic with the
 official fix.
 
 Thanks,
 
 Manuel
