GENERIC crash 11.3-PRERELEASE (i386)

[Schuendehuette, Matthias (LDA IT PLM)]

Hi Konstantin,

BINGO! 110 out of 100 possible points :-)

Yes, that fixed the problem:

root at blnn719x - ~
2048 # uname -a
FreeBSD blnn719x.ad001.siemens.net 11.3-PRERELEASE FreeBSD 
11.3-PRERELEASE #2 r349719M: Thu Jul 11 09:12:21 CEST 2019 
root at blnn719x.ad001.siemens.net:/usr/obj/usr/src/sys/BLNN719X i386

...and I have no doubt that this will work with the current revision as 
well.

Thank you very much!

Best regards - Matthias
