Had seen this failure on Intel before, but not any more. Probably it gets fixed in later kernel version. ------- Additional Comment #1 From Khoa Huynh(khoa.com) 2002-11-06 18:28 ------- 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. ------- Additional Comment #2 From Jeff Scheel(scheel.com) 2002-11-12 15:47 ------- Does this defect fail on RH 7.1 PPC32 bit kernel?
Reassigning to kernel component. Florian La Roche
assigning to ppc maintainer
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.
