Kernel Panic on 4 cores hp c8000

Kernel Panic on 4 cores hp c8000

[Simone Mannori]

Dear All,

I have an HP c8000 with two CPUs (PA-8800, 1GHz four cores) perfectly
working with HP-UX v11: all the hardware is correcly detected and
configured.

I have installed Debian 8.0 "unstable" on a 160G PATA/IDE and on 72G
SCSI disks. Installation looks good, BUT at boot time I have a kernel
panic message (please see below for the details). The behaviour is
deterministic. I'm bootin only with one HD and empty DVD drive.

If you think useful I can post the complete list of boot messages (I'm
working using serial console terminal using Serial_A port).

For the sake of completness, the very same kernel panic arrives using
keyboard and monitor attached to the video card.

The c8000 was perfectly OK with both UP-UX and Linux before the CPU
(from 1 to two PA-8800) upgrade.

Thanks in adavance for your help. In the meanwhile I'm going to
step-back to Debian 5. I will keep up updated.

I think Debian 5 will not even install on the C8000..

But you didn't gave any information which kernel version you are using ?

This kernel should be pretty stable on the C8000:

Correct: the boot DVD hang after a while.

The Debian 8.0 ( "debian-8.0-hppa-CD-1.iso") has configured this kernel:

Linux version 3.16.0-4-parisc64-smp (debian-kernel@lists.debian.org)
(gcc version 4.8.4 (GCC) ) #1 SMP Debian 3.16.7-ckt4-3 (2015-02-03)

I'm attaching the full set of booting message.

Probably you have a more recent kernel because AFTER the installation
you have updated the full distro with more recent packages.
Unfortunately, with this configuration, I can't boot.
I would like to avoid the de-installation of the second processor.

Thanks in advance for your help.

The 3.16 kernel is far too old.
It doesn't even makes sense to debug this kernel any longer, which is why
I said you should update to latest debian unstable (and it's written in the
installation wiki as well).
You have to keep in mind, that the parisc linux port was really nearly stopped
when I built this install CD. Since then we have fixed an uncountable number of
bugs.
So, please update all packages including kernel, glibc and so on.
If you face problems then, please let us know.

You could try to boot with the "nosmp" kernel option (add it at the IPL prompt).
Probably "autofs=off" (not sure if this is the syntax) could work as well (if you think it's the autofs module).

If you have booted up, update kernel and packages.

Re: Kernel Panic on 4 cores hp c8000

[Simone Mannori]

Partial success :-)

Using IPL, I have added "nosmp" option in the kenel command line.
Now the boot finish correctly and reach the command line prompt :-).

I'm updating following the wiki instruction ....

Thanks a lot for the help ...

Re: Kernel Panic on 4 cores hp c8000

[Simone Mannori]

Success: successfull update and boot with new kernel (please see below
for the details)

Respect the instruction presents on:

https://parisc.wiki.kernel.org/index.php/Debian_Ports_Installation

I have only few observations:

- the "/etc/apt/sources.list" must contains ONLY one repository
reference, yours:

    deb http://ftp.debian-ports.org/debian unstable main

- after the "apt-get install debian-ports-archive-keyring" and the
"apt-get update" I was obliged to run

- "apt-get dist-upgrade" because the simple "apt-get upgrade" was not
sufficient.

For the newbie: login as normal user, then switch to "root" using the
"su" command.

Thanks a lot for your very helpful support. I will start to put the
details of this voyage on a wiki page as soon as possible (ASAP).

I installed Debian 5 on the C8000 (using tftp netboot, not DVD) some times 
ago.

It required PCI serial card (because the Debian 5 kernel doesn't recognize 
the built-in serial ports) and PCI network card (the Debian 5 kernel can't 
handle the built-in E1000 network card due to non-standard checksum in the 
EEPROM).

... and the debian 5 kernel was most likely *very* unstable on that machine ? :-)

Yes, it was very unstable. It took long time for the parisc port to 
stabilize.

Recently, I've got some gcc crashes when running kernel compilation in 
parallel with the LVM2 testsuite, so there may still be some stability 
bugs.

I would say it took a change in the way the port is maintained. Helge 
and I communicate
closely.  I look at the buildd logs on a regular basis and try to push 
fixes for gcc problems
aggressively.  This causes some instability but I don't see any other 
choice.  We have also
pushed stuff to glibc.  More needs to be done there but the Debian patch 
set is reduced.

The LVM2 builds on Debian have been generally successful:
https://buildd.debian.org/status/logs.php?pkg=lvm2&arch=hppa
However, it looks as if testsuite isn't being run.

If you find something that is reproducible, please send along.
