Kernel Regen vmunix vmunix.prev kernel size OS panic FLT B800

[Steven Sobkowski]

Hi ..

I opened a call to HP for this but thought I would post a message to see if anyone has encounteres something similar.

System K580 Running HP-UX 11.11 64 bit.

Problem: after any type of kernel regen (even if nothing is changed) the new kernel size is smaller than the current vmunix and vmunix.prev kernel and the system has an OS panic at reboot with a FLT B800.

/stand/vmunix and /stand/vmunix.prev are about 26 MB's in size and boot fine.
The Newly Generated Kernel comes out to be about 17 MB in size and panics when the system attempts to boot from it.

This occurs whether SAM is used to generate a new kernel or kmupdate. If anyone has any suggestions as to what to try I would appreciate it.

There are no errors in any logs. In the system log file howerver, I do get a modadm: DLKM not Loaded error -- but the fix for this problem is to regen the kernel using system_prep and kmupdate -- and when I do that I end up with the 17 MB kernel that panics the system. :(

Good news is you can still boot off the old one if you kept a copy.

I'd look for missing or corrupted system files and such in the /stand filesystem and look for incomplete installation of patches, especially kernel patches, swverify \*

If you look carefully you'll see something you or another admin did that triggered this, or a hardware failure or something.

Steven,

Could you post the output of:

kmadmin -S

Would like to see what loadable modules are there.

Tony --

kmadmin -S comes back with no modules registered.

Steven -- I will try the swverify shortly.

Thanks.
