AW: GENERIC crash 11.3-PRERELEASE (i386)

[Schuendehuette, Matthias]

Hi Konstantin,

thanks for your reply.


I'm in doubt if there is a hardware defect.

If that would be the case, why should the slightly older kernel work?

This (admittedly old) server is running fine with a kernel "r347014" of June 5th, 2019.

The crashing kernel has "r349405", so quite some things have happened in between.

Thanks for the hint with "DDB", I'll try that next week.
As well as narrowing down the first "crashing-releasenumber".

Have a nice weekend :-)


with best regards
Matthias Schündehütte

So your AP (Application Processor) seems to get fault, most likely in the
trap handler.  There were absolutely no changes in the stable/11 in the
area of SMP startup for quite long time.

To get anywhere, you should perhaps add ddb to your kernel configuration
and get the backtrace.  The backtrace would be long, I am only interested
in the first several frames before faults go into recursion.

But, since 1 month earlier kernel worked, and there were no changes, this
might indicate either a failing hardware (your machine is quite old, it
is Core2 Xeon, am I right ?) or problems with your build environment.
