I also edited ttys so I can login via serial. No luck so far. Sti= ll=20 the same result when sending the "~#". But since I now have a real console, I found that not the whole machine is= =20 locked up, it seems just networking is frozen for some time. I still have a very interactive console while networking on the same box is= =20 completely dead. Regrettably sysstat doesn't work vi tip so I can't tell you if there were a= ny=20 interrupts on the network interface during the lock. If you're still interested in some traces please give me a hint how I can u= se=20 the serial debuger (I also had a quick look into the developer handbook, bu= t=20 ddb via serial isn't mentioned) Thanks, =2DHarry > > > Breaking to debugger is working on the console.
