 Ok, I have connected the PX-PH08U drive to the USB port on my laptop,
 mounted its FFS2 filesystem on /mnt, and requested a transition to
 suspend mode again.  As expected, after resuming from suspend state
 the in-kernel debugger was invoked by the system and the next error
 was registered in /var/log/messages:
 
   Aug 17 19:44:32 altair /netbsd: umass0: at uhub0 port 1 (addr 2) disconnected
   Aug 17 19:44:32 altair /netbsd: sd0(umass0:0:0:0): generic HBA error
   Aug 17 19:44:32 altair /netbsd: uvm_fault(0xc0601680, 0, 0, 1) -> 0xe
   Aug 17 19:44:32 altair last message repeated 3 times
 
 Now, I will try to play a bit with the in-kernel debugger:
 
   db> trace
   uvm_fault(0xc0601680, 0, 0, 1) -> 0xe
   kernel: page fault trap, code=0
   Faulted in DDB; continuing...
 
 Sorry, not a very helpful output.  All information was in /var/log/messages.
 The output of ps shows:
 
   db> ps
    PID         PPID   PGRP      UID S   FLAGS LWPS        COMMAND    WAIT
   [...]
   >4              0      0        0 2 0x20200    1        usb0
 
 Best wishes,
 Igor.
