Hi,

on a recent -current using a GENERIC kernel, ifconfig panics when doing

# ifconfig ral0 up

with (typing by hand):

uvm_fault(0xcad4a700, 0, 1) -> 0xe
kernel: supervisor trap page fault, code=0
Stopped in pid 150.1 (ifconfig) at      netbsd:kauth_cred_ngroups+0x6:  movl 0x20(%eax),%eax

Running a custom kernel[1] does not produce this panic.

Best regards,

ND
