Bug#1076309: [s390x] lots of "User process fault: interruption code XXXX"

[Paul Gevers <elbrus@debian.org>]

Package: src:linux
Version: 6.7.12-1~bpo12+1
X-Debbugs-CC: debian-ci@lists.debian.org, debian-s390@lists.debian.org
Severity: normal
X-Debbugs-Cc: elbrus@debian.org

Hi linux maintainers,

Today I restarted the s390x host of ci.d.n because I lost access. I 
inspected the journal and noticed there were a lot kernel messages 
(several tens to hundreds per day) like "User process fault: 
interruption code 003b ilc:3 in my_kmcdump[2aa07980000+f000]". I 
attached the first block I found in the journal after the reboot.

Please let me know if you need more information.

Paul
PS: I checked with carnil before filing this report, he thought it was 
worth reporting.
