Hi,

I get something like a similar bug: when pinging my local gateway, I loose
packets (over wifi (iwl3945) ). Before the update to 2.6.26-rc7 (Debian), I
had no such issues (which makes Internet browsing working but weirdly).

I can't know for sure that my bug is related to the above, but suppose so.
Please ask for details !

Regards, 

Didier Raboud
