Description Simeon 2006-06-27 22:00:38 UTC

 would like to report a strange behaviour of 
FreeBSD AMD64 ver. 6.1. I installed it on a 
QUAD Opteron 846 with Tayan motherbord and 4GB RAM.
I was running SMP kernel. I have an ext2fs partition
where I store all installed compilers and libraries.
I changed directory to my ext3 (ext2fs) partition
and I started compiling one of my libraries. The 
system Hanged. I repeated the same thing with several
other libraries (ATLAS(BLAS), LAPACK, ...) and
everytime
the system hanged. Then I copied the sources to /usr
and I compiled them there. No problem. Everything was
fine 
there. 

I do not know what is FreeBSD AMD64 problem when I 
compile something being in an ext2fs partition since
with FreeBSD x86 I didn't experienced similar 
behaviour. Has anybody noticed something similar?

Best!
Simeon.

How-To-Repeat: mount some ext2fs partition, untar lapack in it
http://www.netlib.org/lapack/lapack.tgz
cd in LAPACK directory and change the makefiles according to 
your platform. Then type make and wait a little bit. You will
see that after 1-2 minutes the system will hang ...
