Hardware Environment:

2 p640 4-way machines (model:7026-B80). One is the client and the other one is
the server.

********************************************************************************
Expected Results: Test should pass.

Additional Information:
Large size file (1.6 MB) doesn't get transferred. Had seen this failure on Intel
before, but not any more. Probably it gets fixed in later kernel version.

Li - per our discussion today, this bug is now transferred to pSeries family.
You will probably want to submit this bug to Red Hat also - please check with
Monica Lemay on the exact process she uses to do this.  Thanks.

Does this defect fail on RH 7.1 PPC32 bit kernel?
Comment 1 Florian La Roche 2003-01-18 09:17:17 UTC 
Reassigning to kernel component.

Florian La Roche
Comment 2 Arjan van de Ven 2003-01-20 19:03:35 UTC 
assigning to ppc maintainer
Comment 3 Guy Streeter 2003-01-27 19:02:00 UTC 
LTP is not a product in the RH 7.1 distribution.

------- Additional Comments From lge.com  2003-01-29 11:24 -------
LTP is not a product of RedHat 7.1, but the sendfile() system call is.  The 
test is failing with large transfer sizes. This is most likely a kernel issue 
that can easily be resolved by going to a more recent kernel. If RedHat wants 
to close the bug, they can, but the problem will ALWAYS exist in their 7.1 PPC 
release as long as it stays with its current kernel version.
