Package: linux-2.6
Version: 2.6.18.dfsg.1-12, 2.6.18.dfsg.1-12etch1
When upgrading to the etch version of the kernel, I noticed a complete
NFS lockup as soon as a client tries to write something.
I tracked this down to the TCP layer; I'm using jumbo frames (tried with
MTU ranging from 2000 to 7200) and all *received* TCP packets exceeding
1500 bytes are simply dropped. They don't even appear in tcpdump. This
does not affect UDP nor ICMP packets, and this does not affect sent TCP
packets.
It is a regression from 2.6.18.dfsg.1-8, and I think it is related to
the r8169 changes introduced in -9, as the network controller is a
D-Link DGE-528T using this driver.
Cheers,

Closing the bug for now. If anyone manages to reproduce with
a more recent kernel, please reopen.
