Here on a b180 running 2.6.11-rc3-pa3 (while the system should be idle)

Any idea about known ext3 pb?

Long time ago I have seen a couple of those. I can't remember what
exact kernel version(s) it was, but it happened with the earlier 2.6
kernels.
Pretty much the same output (I think I once posted it on the mailing
list), but I only got this when I tried out some graphics card (ATI,
Voodoo2 or Matrox?) and shortly after xdm started (and not every
time). I think 64bit kernels triggered it more easily.

But I haven't gotten one of those lately (at least not with 2.6.10-rc1
and later, with Matrox graphics card).

> Any idea about known ext3 pb?

Good question. I have a different problem than the one above: In very
rare occations, when transferring very big files onto a USB-hdd
(ext3), the files are being silently corrupted (no kernel log
messages). But I don't know whether that problem is related to ext3 or
usb-storage or a faulty h/w.

Back to your problem: I don't know/think that there are any severe
problems with ext3, at least I was using it on PA for a long time and
it worked quite well. But there is always the possibility that there
are some hidden bugs that are triggered in rare situations however ...


Greetings,
  Max

Got hit by a similar panic during the night (the kernel uptime was < 5h)

Kernel Fault code 15
Top stack was:

cache_grow
cache_alloc_refill
kmem_cache_alloc
journal_alloc_journal

and the rest was identical to your dump.

IAOQ was alloc_slabmgmt and gr2 was cache_grow

This was 2.6.11-rc3-pa5 freshly built with Kernel Hacking turned off.

I just come back because after a second read, it looks like the b2k pb re=
lated
here:
<http://lists.parisc-linux.org/pipermail/parisc-linux/2005-February/02587=
0.html>

mmm hard to say if there are actualy the same?

That said, today same panic (as related above) on b2k  32bit  but not on
b180 with the same 2.6.11-rc4-pa1 (cvs dated 20050217).

By chance, I can save a top info at the crash moment:

The time stamp seems to tell me to look into cron daily ...

I will try to locate this 'find' task (probably locate db update) and see=

if I can reproduce ;-)

Thanks,

Kernel panic - not syncing: Kernel Fault

This time while 'apt-get dist-update' on a chroot disk :-(

I tried to reboot but pdc didn't find any more boot devices:
...
Main Menu: Enter command > sea
...
   Path Number        Device Path              Device Type
   -----------        -----------------        -----------
Error detected on single-ended FWSCSI interface.
No devices found.
...

even after a reset.
I have to cycle power off/on the external disk (a fw scsi disk connected
to the fw ctrlr) to be able to reboot then complete the apt update withou=
t
any pb??

mmm no such device available here to make test (sorry) (on a b2k obviousl=

;-) )

Considering the strange status in which was the external disk, it should
be possible to be some h/w failure demonstration occuring from time to ti=
me??

The same for me ;-)
