 Running with the uvm guard patch:
 
 Two CPUs show:
 __kernassert() at netbsd:__kernassert+0x2d
 fd_ofile_free() at netbsd:fd_ofile_free+0x6f
 fd_copy() at netbsd:fd_copy+0x22e
 fork1() at netbsd:fork1+0x7f5
 sys_fork() at netbsd:sys_fork+0x32
 syscall() at netbsd:syscall+0xb6
 
 A third one:
 copyout() at netbsd:copyout+0x52
 uiomove() at netbsd:uiomove+0x63
 tmpfs_read() at netbsd:tmpfs_read+0xde
 VOP_READ() at netbsd:VOP_READ+0x66
 vn_read() at netbsd:vn_read+0x9f
 dofileread() at netbsd:dofileread+0x80
 sys_read() at netbsd:sys_read+0x72
 syscall() at netbsd:syscall+0xb6
 
 The failed assertion is:
 kernel diagnostic assertion "n > NDFILE" failed: file 
"../../../../kern/kern_descrip.c"
