Reboot after panic: post_hndlr(): Unresolved kernel interruption

[UJOSHI]

Hello Admins,

One of my HPUX 11.23 ( RX 7640 ) is behaving very strange.

From last 10 day its getting reboot everyday around same time ( 12:05 Noon )

1) Syslog showing nothing strange.

2) no cron scheduled that can cause this panic reboot at this particular time.

3) everytime crash dump is generated.

4) No major hardware event logs.

I have created crash.html with command 

./crashinfo -t -H -continue > crash.html

The buffer messages while panic reboot are below:

Calling function e0000000011884c0 for Shutdown State 8 type 0x2

Stored message buffer up to panic:

What does it mean?

/etc/shutdownlog- show the message "Reboot after panic: post_hndlr(): Unresolved kernel interruption"

Can anyone let me know what is causing the panic reboot everyday? Let me know for further any assistance.
