What steps will reproduce the problem?
If possible, include a link to a program on play.golang.org.
1. build golang on tip on x86_64 port, 6g etc.
2. run all.bash
3.

What is the expected output?
all test is supposed to pass

Which compiler are you using (5g, 6g, 8g, gccgo)?
6g

Which operating system are you using?
slackware linux 64 bit

Which version are you using?  (run 'go version')
go version devel +7359dad2971d Wed Jan 09 22:03:41 2013 +0100 linux/amd64

Please provide any additional information below.
for some reason other people running 64 bit hasnt been able to reproduce it. I am using
the latest kernel 3.8rc2 if that matters, otherwise, i cannot think of any software
updates ive done recently.

Comment 1 by tobyjwebb:

Unfortunately, it looks like using the 3.8rc2 kernel does matter. I had the same
problem, which disappeared when using the stable kernel (I was using 3.8.0-rc3 at the
time the tests failed):
Linux c850 3.6.11-1-ARCH #1 SMP PREEMPT Tue Dec 18 08:57:15 CET 2012 x86_64 GNU/Linux
The source I'm using to compile is:
changeset:   15373:e55f615005ba
We'll have to wait to see if the issue still shows up in kernel 3.8 stable...

Comment 2 by qeed.quan:

all the tests have passed with the kernel 3.8rc4, seems to be a kernel issue rather than
a go one.
