pptp floods syslog

[sodb]

Running Olegs 1.9.2.7-2. Already had same problem with 1.7.5.9-5 that syslog (dmesg) shows this

I use PPTP to connect to a Speedtouch Home (for some reason the internal ppp connection of the modem gave up, so I have to use PPTP).
Is this debugging output of the ip_conntrack, or what is this? Can it be switches off?
Other question: is it normal that at download speed of aprox 1Mbit/s the pptp proces claims approximately 25% of the cpu load?

Yes, this is debug output, turned on by ASUS.
Try 1.9.2.7-3b, I've lowered the level, so debug messages should not appear in the log.

With 1.9.2.7-3b the syslog looks much cleaner now. Thanks for this!
