Greetings all, I'm running a snapshot of NetBSD-CURRENT as given by 
uname -a "NetBSD athlon1000 2.0F NetBSD 2.0F (GENERIC) #4: Sat Jun 26 
03:40:22 GMT 2004  
roman@athlon1000:/usr/obj/sys/arch/i386/compile.i386/GENERIC i386" and I 
experience frequent system lock-ups druing heavy I/O operations on UFS2 
filesystems mounted with "softdep" option. The system hangs at random 
times and the only thing I can do is to reset it. I have disabled 
"softdep" on all mounted filesystem and the frequent lock-ups have 
stopped, however the filesystem performance is worse without "softdep".
My question is has anyone experienced the same problem, is it a well 
known bug, where should I look for the cause of the problem?

Thanks
