 More information:
 
 I recreated the filesystem without the huge -f (avg filesize) option,
 which we had initially set to 1Gb:
 # newfs -U -O2 -b 8192 -f 1024 
 # tunefs -e 20480  (10x the default)
 
 With the defaults of avg filesize of 16384, we don't see a crash. I
 then started playing with tunefs.
 Increasing the avg filesize to -f 16777216 (16Mb), we don't see a crash.
 Increasing the avg filesize to -f 33554432 (32Mb), we repro the crash.
 
 By the way, cvsup was performed at around Nov16 23:00 UTC, I can
 probably find the exact timestamp if needed.
