Hi, 

funny problem w. 2.5.43-mm2:

i'm running 2.5.43-mm2 on my workstation. Normal workload, X-windows, a few
xterms, editor, mozilla, etc. (host A)

I have a NFS/SAMBA-mount (both show the problem) to host B. Host B runs
2.4.19rc5aa1.

I can get a xterm, in which i have a ssh-connection to a third host C
'stuck' by simply cat'ing a large file from the NFS/SAMBA server to
/dev/null.

The xterm/ssh seems stuck, that is no key i press is received on the other
end, but output of the program running on host C is updated in the xterm. I
checked with tcpdump: the keypress does not generate a packet, my host only
sends ACK's on that ssh connection to host C.

The ssh-connection is not unstuck by stopping the data transfer from host B.

I checked that plain 2.5.42 and 2.5.43-mm1 do not have this problem: here my
input goes through to C. At least for small amounts of input, i did not test
anything beyond typing a few hundret chars.

recap:

 "mount /mnt/hostB"
 "ssh hostC" -> type random stuff in that connection
 at the same time do "cat /mnt/hostB/bigfile > /dev/null"
 ssh gets stuck.

hardware: PIII/600, 3c905B on 10baseT half-duplex

I'm sorry i cant do any further checks until Friday afternoon (MET).

/B.
