menu is not available for woody because it's written in a language which
bears a passing resemblance to C++. someone rewrote it in C++ for
sarge.

I agree.

The only other uses for __ldcw are the SPIN_LOCK macro in atomic.h
and the _raw_spin_trylock in spinlock.h (i.e., it is only used
acquire locks). If all these need barriers, then it might as well
be in __ldcw.

I told Grant, that at my current schedule, it would be 2006
before I fixed this problem :)
It looks like a reordering issue, perhaps taking a look at the
respective .o objects produced by the two compilers might reveal the
issue. I think that's the way we did it when the tty layer broke and we
had to have that console.o compiled with 3.0.4 by hand? I think Randolph
and Grant worked on that together. I might have the wrong names, but
we've successfully debugged a problem like this before using similar
methods.

My schedule isn't much better. I'm off to Tokyo at the end of the week
to waive the Canadian flag at the ISO LRG meetin next week. After that,
my brother's company would like me to work on more firmware for a new
project.
Is this on a SMP kernel (i.e., could this be a locking issue)?

I downloaded the "debian-30r2-hppa-binary-1.iso" and burned it to CD.
If I start the installation on my C240 (fx4) workstation with the
command:
bo sescsi.2.0
it seems everything ok, until I get the message:
..If this is the last message you see, you may need to switch your
console.
This is a common sympton sarch the FAQ and mailing list at
parisc-linux.org
After this nothing happens anymore.
I searched the FAQ and mailing list but I could not find a solution.
Anyone who can help?
Thanks in advance.

no. I don't build or run SMP kernels on anything at the moment.

FX-4 graphics is not supported.
Either use serial console or replace the FX4 with PCI FX-E.

Hi Grant, Christoph,
I find a fix for this pb. I tested successfully (I reach to login with a
ttyB0 after replacing ttyS0 in inittab and telinit q :) ) on a 32bit 2.4
kernel on my b2k and a 64bit (up) [also 2.4] kernel on my N4k.
