i have seen this too. worse yet, the only way to restore the proper state is
a power cycle. even doign a restart and full tests wont properly reset 
it. Also, once it's in this state, the device is 99% unusable by VMS as 
well, i wanted to see if VMS would put it back in its right mind, but it
doesnt. instead, VMS will every few minutes get very slow for maybe 10-20
seconds. also, the sgec under vms will then let only a coule of frames
through and then freeze for anywhere from a minute or so to ten minutes or
so. this just happened to me a day or two ago on a 4600 with kernel 
1.5S.
