Is it a customised kernel ? The kernel is a stock debian amd64 kernel, not customised by me. I did build the r8168 from the realtek site. bit more info on the setup I have 2 laptops (both HP's), 1(A) running Vista 1(B) running Debian lenny/= sid (2.6.25). I have three servers 2 shuttles (forcedeth) (multimedia & hufpuf = ) 1 gigabyte (realtek) (nas). The nas box is the one I coped the error from the syslog. it is primarily a nfs nas. Hufpuf is the samba box, it used to be the nas box. it currently mounts a few (large) shares from nas. Multimedia is a backup server. A & B & NAS have 1500 MTU multimedia and hufpuf can run with 9100 mtu I have tried i) coping files from A to hufpuf (smb) which then sends it on to nas via nfs ii) copy files from B to nas (nfs) iii) scp from B to hufpuf and then on to nas via nfs iv) scp from B to nas v) scp from hufpuf to nas vi) scp from hufpuf to multimedia vii) scp from multimedia to nas viii) hufpuf nfs to nas ix) multimedia nfs to nas all of these have caused these errors. when I was testing again today, I noticed when I was coping from A to hufpuf and then onto nas. that smaller files say < 200M would go okay, anything greater (or if the total of the files was greater) then I would start to get the errors. =20 >=20 > [...] > > Help >=20 > Don't panic. not panicing yet but I am a bit concerned. the data seems to be okay even after these errors >=20 > --=20 > Ueimor >=20 --=20 "You see, the Senate wants to take away some of the powers of the administr= ative branch." - George W.
