[parisc-linux] Same boot problem on a 9000/720/50 HP machine as on 712/60 of Niskanen

[parisc-linux] Same boot problem on a 9000/720/50 HP machine as on 712/60 of Niskanen

[Christoph Plattner]

On my 9000/720 (I have it since one week) I have the same problem
booting the CD 0.5
or
a selfbuild kernel. The kernel boots, but on calling the
init a trap is called with the text:

handle_interruption() pid=1 command='init'

     YZrvWESTHLNXBCVMcbcbcbcbOGFRQPDI

and so on, running in a loop.


The code is in kernel/traps.c

Further I tried to build a statically linked bash-2.03,
but I had problems setting up the build process to produce
a HP PARISC user program. What I have to do to setup or
prepare default source trees for cross building (the
compiler runs....)

Yes, several people(myself included) saw this. IIRC a newer kernel fixes it.

Which compiler are you using? You can grab a prebuilt hppa cross-compiler 
(that runs on i386-linux) at,

ftp://puffin.external.hp.com/pub/parisc/binaries/LinuxX86/xc-latest.tar.gz

bash is particularly hard to build. I was able to get the debian package to 
cross compile using the dpkg-cross tool and by making a few changes to the 
source tree. I still need to test the binary, if it works I'll post it.

Ok, I got bash to build static against the glibc in the xc and I setup an 
nfsroot with bash as my init. I am using a new kernel built with the same xc. 
Here's what I get when booting,

and it keeps looping with that same error.

The bash I'm using is at

The xc I'm using is at

ftp://puffin.external.hp.com/pub/parisc/debug/xc-20001222.tar.gz

I think the kernel and libc have different world views. I can provide 
different bits on request.

Any ideas?

[Christoph Plattner]

What is a newer kernel  ?
Date, version ?
What does IIRC mean ?

Ad tool-chain:

        I use the tool-chain of the puffingroup, selfmade from the
        latest version of 21.12.2000 or so. I build it from source
        and it was no problem except the fact, that the it must be
        `--host' not `--HOST' (I have some experiences in it).

        But it was not possible to build bash from the scratch in
        this way. host=hppa-linux, build=i386-linux should be the
        correct one, but ....
        The biuld process of bash (and I think for other too,
        does not call the cross compiler). The use of CC= AS= LD=
        etc has the other problem, that binary tools which are build
        in the build process are running on PA RISC, but they are used
        in i386 for further building.

        So my question: How can I tell an autoconfigured build process
        (standard linux source tree) to use the cross compiler on the
        right points.

	As I used RedHat up to now, I have no experience in
	debian packaging system. What are this files like
	dpkg-cross tool, etc...
	How to use them, how to install them.

	You say, the bash is a problem. Is this for other tools
	much easier, like `init' or daemons, etc...

Thanks for the help and a happy new year soon....

	Christoph Plattner

I also just tried booting an old nfsroot, then trying to run the static bash. 
Here's what I get,

Just to see how bad the problem was I built helloworld and it runs ok. I'll 
try to narrow it down more than that :)

It seems to just be the xcompiled static bash I built. I xcompiled sash and it 
worked ok. I setup an nfsroot with a bunch of stuff I had cross-compiled and 
except for bash and a couple other things, it's working normally. I will try 
compiling bash native and see if that helps.

OK, since I have a mostly-working nfsroot and a cross-built toolchain I tried 
running gcc. I just tried "gcc -o hello hellow.c" where hellow.c is the hello 
world program from cvs->userspace. The compiler dies with signal 6(abort). The 
system is also pretty erratic, sometimes the prompt takes a few minutes to 
return.(once with an out-of-memory error)

Someone suggested that I try an older kernel from before the stack changes 
were made eariler this month, so I tried an old kernel I had around(built with 
an old xc). Now gcc gets a little further, but dies with,
