Hi Bastien,
Please edit the /etc/sysctl.conf on your machine and
add/adjust/uncomment the following line..
ddb.console=0 # 1=Permit entry of ddb from the console
By default, you could escape to the ddb/KDB from the console.
Activity on the serial port like a reboot on the other side of the
serial cable can trigger that escape.
I allways disable ddb.console now. Bitten too often in the past.
Cheers
Y.
Quoting Bastien Durel <[email protected]>:
Hello,
I have a Soekris Net-4501 running flasboot/OpenBSD-4.5
uname -a
OpenBSD fremen 4.5 SOEKRIS4501#0 i386
when I connect a NULL-modem cable to an USB serial port, I often
experience kernel panics.
They can be "solved" by typing 'c' on the KDB console. But I must be
physically present. Sometimes it hangs when I'm remote, if the cable is
plugged -- especially when the attached computer is shut down.
Have you experienced these kind of problem ? Is there a trick to not
suffer them ?
Regards,
