 Interesting.  What kind of disk do you have?
 
 In crash(8) or ddb, can you get the kernel stack trace of the rndctl
 process?  In this case, the pid is 633, so it would be:
 
 crash> bt/t 0t633
 
 (Note the `0t' prefix for decimal.)
 
 I bet it's going to come up in sys_fsync_range, which is going to
 reveal a problem with fsync_range(FDISKSYNC) on your disk controller
 or hard disk.
