[parisc-linux] kernel panic when extracting large tar files

[parisc-linux] kernel panic when extracting large tar files

[Vlad D. Markov]

When I extract large tar files on my 735/99 (tar --numeric-owner -xzvpf ), 
the kernel panics and I get a core dump.

My kernel is: Linux version 2.4.20-pa18 (root@grumpy) (gcc version 3.0.4) #22 
Fri Dec 27 21:25:37 EST 2002

I saved a capture from minicom and have not upgraded the kernel since. I can 
mail the capture and my System.map separately.

If a new kernel or different version of gcc is needed, please let me know.

Interesting, can you explain me how do you grab this coredump?

Firstly the minicom capture, would already tell more :)

which say that is a trap 5 (ie a LPMC). So, may me am i wrong, but it see=
ms
that there is a hardware problem on this machine?

AFAIK to analyse this kind of problem would be to re-install (may be a te=
mporary
external disk) hp-ux and mainly DIAGTOOLS.

On my own a run 2.4.20-pa18 (2.4.21-pre2-pa18) (compiled with same gcc)
without problem on a b180 and b2k (excepted with PDC on this last).

But again I am not expert so I made ml in CC.

Cheers,
    Joel

yes. LPMC is usually a recoverable memory parity error.
ISR/IOR is the virtual address that was accessed.
Since this is kernel space (ISR==0), I think you can just
drop the leading 1 for the physical address.

Try pulling half the memory and see if the trap goes away.
Or replace all the memory if you have spares.

Well,

after having talked a bit with the 'pioneers' here at ESIEE, it appears 
that this tar problem is a long lasting one.

Matthieu Delahaye told me that since the very first days of pa/linux; 
this bug has existed, mostly happening on 'un-taring' files, obliging 
users to untar by small chunks of data.

FWIW, I experienced that bug too on the A500, had no time to chase it 
down but I will look at it soon.
It's near the top of my TODO list :)

And hardware errors have existed since the beggining of time ;)

How big is the file? I routinely tar/untar _very_ large source archives
on my A500 and I see no problems.

Hardware errors happening on several boxes and only when unpacking an archive?
Kinda "feature" heh ? :)

About 700M gzipped.

I just unpacked 1234744157 Jan  7 19:33 src.tar.gz into a 4GB source
archive on an ext2 fs. The box didn't even blink. Running 2.4.19-pa22 
parisc64 non-SMP.

As it turns out Vlad's archive is on 14MB's but contains lots of very
small files. I'm trying to get a hold of this to test it out.

I just downloaded the archive that Vlad had problems with and it doesn't
crash my machine. We'll need some more detailed info about the hardware,
scsi setup, and the procedure.
