[adding linux-kernel again]

OK, first show us (that is, the mailing list "linux-kernel@vger.kernel.org", not
just me) what your "kernel-build-script" looks like.

The beginning of the log files that you sent to me (at end of this email)
is very suspicious looking. It looks like you are not using the expect kernel
build procedures.

The crash problem (snippet below) is a fault in xor_sse_2() in the function
that tries to choose the best (fastest) xor method. I would expect other
people to be having a similar problem. I don't suspect that it's related to
the build problem (Makefile.o), but we need to have you building kernels

Hi Sam,

This is somewhat of a build regression... a confusing one to me.
Maybe you will know what it's up to.

There's also a kernel boot regression: something in
crypto/xor.c::calibrate_xor_blocks() finds a null pointer.
I can't reproduce it. [more below]

Werner, for the machine that crashes during boot, please send us
the contents of /proc/cpuinfo. Thanks.

(BTW, for anyone reading along, vger sees Werner's emails as spam,
so you may receive mail directly from him instead of seeing it on
lkml.)

Werner's kernel-build-script is a large multi-purpose script with

which I can easily reproduce by doing (at kernel top-level dir):

make defconfig
make -B

This does not happen in 2.6.23. Instead, that sequence just loops
forever with: (this is what I get:)
