hi list,
.. i recently upgraded my dsl-gw-box to 3.8-beta (from 22th aug)
and today (after ~1week of uptime) it now paniced with a duplicate free.

this is pretty odd, since i know of some other 3.8 boxes which are
running just fine; so just in case that matters ... imho the only
difference here is that my box is doing (kernel-)pppoe to an
upstream-isp and in turn often has to "redial" it's connection
(eg. its doing a lot of ifconfig up/down/destroys via some watchdog
cronscript in case it detects a dead uplink ... yes ugly and stuff,
but it usually just works(tm) :-)
so ..
any insights/ideas/advices? b0rked hardware? known bug?
thx,
alex.
ps and dmesg follows ...
