I'm using rocket.o 1.08 with a bug-fix patch that is in 1.09B1.
Both oops's in the past few days have been followed by:
Attempt to open closing tty ttyR46.
Ack!!!! This should never happen!!
though the tty has been different. Both times it's been the original
name of a RocketPort tty, even though I rename them at bootup immediately
after setrocket creates them. ttyR46 ends up being named ttyRK.
Each time, this seems to have happened immediately after a copy of pppd
2.1.2d started.
Here's the output of today's pair of oops's generated by ksymoops and the
original log entries. I don't understand the Code: lines but I did
verify with my own perl script that the Trace: information is correct.
Using `../System.map-1.2.13-hp' to map addresses to symbols.
