does this still happen in current trunk?

comment:2 Changed 3 years ago by anonymous

at least on r45415, yes

comment:3 Changed 3 years ago by nbd

please post the updated crash log

comment:4 Changed 3 years ago by GregorHoffleit

For what it's worth, I get this crash on a Netgear WGT634U running Barrier Breaker (r42625) reproducable, whenever I run the "KabelBW speed test" (http://www.kabelbwbusiness.de/anforderungen-speedtest.html) from a client of this router.

I haven't yet tried with a more recent build.
