Kdump +crash - Debian

Fórumok

Sziasztok!

épp kdump-ot állítok be egy régebbi szerveren (Linux P 4.19.0-6-686-pae #1 SMP Debian 4.19.67-2+deb10u1 (2019-09-20) i686 GNU/Linux), kisebb nagyobb sikerrel és a segítségeket szeretném kérni.

A crash dumpok létrejönnek egy kiprovokált kernel-panic után, viszont nem tudom megnézni a dump fileokat. Crash file-ok:

Az egyikről bővebben:
# file ../201910171214/dump.201910171214
../201910171214/dump.201910171214: Kdump compressed dump v6, system Linux, node , release 4.19.0-6-686-pae, version #1 SMP Debian 4.19.67-2+deb10u1 (2019-09-20), machine i686, domain (none)

A crash meg sem tudja nyitni a dump-ot, mert szerinte nem matchel a kernellel:
# crash /usr/lib/debug/lib/modules/4.19.0-6-686-pae/vmlinux /var/crash/201910171214/dump.201910171214
