I can't reproduce that (2.6.0-test3 + ia64 patch). I also ran it
twice with the same arguments and it ran to completion both times.
What compiler do you use?

I compiled the kernel with the debian unstable gcc 3.2:
Reading specs from /usr/lib/gcc-lib/ia64-linux/3.2.3/specs
Configured with: ../src/configure -v
--enable-languages=c,c++,f77,objc,ada --prefix=/usr
--mandir=/usr/share/man --infodir=/usr/share/info
--with-gxx-include-dir=/usr/include/c++/3.2 --enable-shared
--with-system-zlib --enable-nls --without-included-gettext
--enable-__cxa_atexit --enable-clocale=gnu --enable-objc-gc ia64-linux
Thread model: posix
gcc version 3.2.3 (Debian)
if it matters this was a bk pull from linus's tree that claimed to be
2.6.0-test3...
also is there any reason i did not get more of the stack trace from the
kernel?

OK. While I don't use this compiler myself, it should be OK.

That should be OK. I did release an ia64-specific patch in the
meantime. I don't really expect it to make a difference for you
problem, though (you might want to try it just to be on the safe
side).

It might indicate stack corruption. Which brings me to the next
question: what filesystem were you using? I used ext3.

ok, i'll try the patch, but from your change long i did not see any
issue there either.
I am using an ext3 system, which was made under 2.4.XX before i
installed the newer kernel. This test is run in the root filesystem if
that makes a difference.

OK, so it's not Lustre (otherwise, I'd have suspected a stack
overflow... ;-)

Same for me.
Is there anything unusual in your config (e.g., page size other than
16KB)?

I tired not to do anything strange, i place the .config at
http://felix.homeip.net/2.6.config if you wouldn't mind taking a look.

It looks mostly fine to me. I see several SCSI drivers are enabled.
Which one actually talks to the test disk? SYM53C8XX_2?
One thing I did notice: It's configured for Itanium (Merced) instead
of Itanium 2. That will definitely slow things down, though the
resulting kernel should work correctly. I'd recommend to change that
to Itanium 2 (McKinley).
