Thanks for responding - will do. I verified with 2.6.24-rc4 (same bug) and
have some new information about this.
Despite my previous posting the corruption is NOT triggered by NAPI. It
may be related, but even without NAPI but tso on again I got corruption,
now also on the gbit client (Thinkpad T60). When ftp'ing to ramdisk with
full speed (at a reasonable ~77 MB/sec) it "often" works, but intermediate
writes that cause the ftp to temporarily slow down reliably cause
corrupted files, so I guess tso gets confused when some kind of throttling
sets in during transfer. That is probably why I first noticed it on the
slow 100mbit client.
Maybe turning off sendfile or NAPI just lead to random success - so far it
really looks like tso on the r8169 is the common cause.
thank you
Holger
