My apologies. I'm well aware of the purpose of -current vs -stable. I was more concerned with the fact that it appears to be possible to get the DPT controller so scrambled up that a simple reboot doesn't reset it. Not anything with SMP/3.0... FWIW, I can still crash SMP/3.0 if I bump up InetLoad high enough, but I still can't crash a 3.0-uniprocessor kernel with no MAXMEM... Haven't supped since yesterday, given the headaches of applying the DPT patches all the time to the sys tree. I don't see this so much as a 3.0 problem, as a DPT issue, but I could be off base. Wouldn't be the first time... :0 On Fri, 5 Sep 1997, Steve Passe wrote: > Hi, > > > Using DPT-1.2.4 with 3.0/SMP. > > > > I was running a test of adding 25000 accounts and removing them, and > > making sure everything was hunky-dory, when the dreaded: > > > > "DPT: Undocumented Error" > > db> > > > > Occurs. > > > > OK, Happened in the past.
