Magic number wrong (namelist mismatch?)

Bill, have you rebuilt a kernel, moved into place, but not yet rebooted?
This is normally where the in-core kernel and the on-disk kernel do not match.
Lanscan will also usually give something similar

Oopsie, this message usualy comes from a binutil like command like strip, nm, ar, ld and such.

Can it be that there is an architecture mismatch for some binary? Did you copy an 11.00 binary to a 10.20 or a hppa-2.0w to a hppa-1.1 machine?

And excuse the heck out of me, why can't this error message say what it really means?

UNIX can be so darn infuriating and cryptic at times. It is almost like they are intentionally obfuscating this instance.

Just rebuilt the kernel as mentioned...
works fine after reboot.

thanks

Or you can just move the new kernel away, and move .prev back:

mv /stand/vmunix /stand/vmunix.new
mv /stand/vmunix.prev /stand/vmunix

Then you can reverse this later if you still want to reboot and apply the changes.
