linux-crashdump 5.19.0.21.21 (s390x binary) in ubuntu kinetic

 This package installs all the needed infrastructure to get crashdumps from
 your running system. If you are experiencing kernel crashes that cannot
 be debugged normally (because the problem is infrequent or panic's the
 system in such a way as to make information gathering impossible), then
 you can install this package to automatically enable capture of the
 vmcore on crashes.
