possible dupe of #209420
I agree -- it looks just like #209420 -- sorry I didn't spot it when scanning before reporting the problem :-( The patch seems scaringly simple (i.e. allow it to sleep!)
Fixed in 2.6.18-1.2759.fc6, so feel free to close the ticket. Thanks. teith:~: echo CBA>tmp/n;od -c tmp/n;ssh -n -x greta echo X\>tmp/n;od -c tmp/n 0000000 C B A \n 0000004 0000000 X \n 0000002 teith:~: uname -a Linux teith.cl.cam.ac.uk 2.6.18-1.2759.fc6 #1 SMP Tue Oct 10 17:34:23 EDT 2006 x86_64 x86_64 x86_64 GNU/Linux teith:~:
