Thanks very much for the instructions, Stefan. I followed them carefully 
and THINK I've installed your new kernel. dmesg shows this line..

Linux version 2.6.24-21-generic ([EMAIL PROTECTED]) (gcc version 4.2.3 
(Ubuntu 4.2.3-2ubuntu7)) #1 SMP Tue Aug 19 22:34:58 UTC 2008 (Ubuntu 
2.6.24-21.40smb3-generic)

I removed my over-ride for net.ipv4.tcp_frto and after booting your 
kernel, it had acquired the default value of 2.

Sadly, my job did not print - it appeared to hang for ever and certainly 
was still going after 10 minutes. I then cancelled the job, changed frto 
to zero, power-cycled the printer, resubmitted the job and it printed 
successfully within a few seconds.

So who made a mistake? The alpha 4 Intrepid kernel prints OK, but this 
Hardy system does not.

Did I do the install wrong, or did you send me a kernel that did not 
have the complete fix?

I've captured sniffer traces of the successful and hung TCP sessions. 
Your kernel seems to be behaving slightly differently to the current 
production Hardy version.

Under 2.6.24-19, the printer is completely hung because the protocol is 
so garbled - the retransmissions and duplicate acks eventually get 
"stuck" so the session never makes any progress beyond a certain point.

However, under your modified 2.6.24-21, it looks to me (provisionally) 
as if data is still managing to be transferred even though the protocol 
is seriously broken. When I cancelled the job it had managed to transfer 
and acknowledge 1500 bytes in the previous 4 minutes. Perhaps if I had 
waited a couple of hours, the job might have completed!?

I await your thoughts with interest.

Brian
