Hpux 11.23 server panic: post_hndlr(): Unresolved kernel interruption

Hi,

 

I have 2 servers ,both of them have given panics in different days

 

The panic in both of them are exactly the same, they have the same stack trace:

 

panic: post_hndlr(): Unresolved kernel interruption

Stack Trace:
  IP                  Function Name
  0xe00000000052f310  post_hndlr+0xc80
  0xe00000000052e220  vm_hndlr+0x210
  0xe000000000bc0a40  bubbledown
  0xe0000000005fa810  qenable+0x10
  0xe0000000014261a0  td_dumpdev_unconf+0x5970
  0xe000000000810110  sq_wrapper+0xf0
  0xe000000000b712b0  str_sched_mp_daemon+0x810
  0xe000000000b6f5a0  str_sched_daemon+0x3a0
  0xe000000001017cc0  im_mpnetstr+0x60
  0xe00000000144e410  DoCalllist+0x3a0
End of Stack Trace

 

Really looks like a patch problem, since they have a very old QPK, but I have been looking around in the kb I can't pinpoint exactly watch patch is needed to solve the problem,we first need to find the bug so we can justify a patch update

 

Both have the same same level of OE and patches installed:

 

 HPUX11i-OE-Ent	B.11.23.0609   HP-UX Enterprise Operating Environment Component 
  QPKAPPS		B.11.23.0609.053a Applications Quality Pack Bundle for HP-UX 11i v2, September 2006 
  QPKBASE		B.11.23.0609.053a Base Quality Pack Bundle for HP-UX 11i v2, September 2006

Re: Hpux 11.23 server panic: post_hndlr(): Unresolved kernel interruption

are you loading a dynamic kernel module at time of panic?

 

I only ask, because your footprint matches PHKL_31500

Re: Hpux 11.23 server panic: post_hndlr(): Unresolved kernel interruption

Hi

you probably need to ask to "td_dumpdev_unconf"  vendor.

 

Looks like you probably have some 3rd party vendor streams driver install.

 

Best regards

Re: Hpux 11.23 server panic: post_hndlr(): Unresolved kernel interruption

Hi,

 

Thanks for the answer. I can't find any third party software installed that loads modules, I don't see any module in kcmodule that stands out.

 

The only third party software installed is a backup client that doesn't load any drivers.

 

I have attached the kcmodule ouput, to se if you can help me trackdown which is the 3rd party soft.

>you probably need to ask to "td_dumpdev_unconf"  vendor.

 

I find this entry on both 11.23 and 11.31:

$ nm -pxAN /usr/conf/*/* | grep td_dumpdev_unconf

T  /usr/conf/lib/libtd-pdk.a[td_dumpdev_real.o]:td_dumpdev_unconf  (11.23)
t  /usr/conf/mod/td:td_dumpdev_unconf   (11.31)

 

>because your footprint matches PHKL_31500

 

I'm not sure that's related since ALL customers on 11.23 should have that omnibus patch in 2004.

While I see post_hndlr, I don't see that stack trace.

Yes, all 11.23 since 2004 have that patch, it's when pa-risc was added to 11.23.

 

I can't relate it with a third party stream module

Sorry, I posted, without adding info, I have the same output:

 

0x0000000000000010 T  /usr/conf/lib/libtd-pdk.a[td_dumpdev_real.o]:td_dumpdev_unconf

> swlist -l file | grep -i /usr/conf/lib/libtd-pdk.a

Re: HP-UX 11.23 server panic: post_hndlr(): Unresolved kernel interruption

indeed you are right, what make me feel there was a 3rd party is that I never saw

td driver using streams framework.

  0xe0000000014261a0  td_dumpdev_unconf+0x5970
  0xe000000000810110  sq_wrapper+0xf0

 

so probably there is a static function after td_dumpdev_unconf which caused the panic.

So if you have PHKL_31500 on your system this need to be analyzed by hp support.

disassembling around that adress will be necessary.

Ah, yes, the large offset from td_dumpdev_unconf.  But I would have thought that the kernel stack trace function would handle static functions?

But likid0 never mentioned whether it was PA or Integrity.

 

Possibly gdb would work for either?

gdb /stand/vmunix

Hi Dennis, sorry I forgot to mention, this is a Itanium server.

I had also seen it in the crashinfo trap section,but couldn't find any info on it. I have also attached it
