Donenfeld <ja...@zx2c4.com> Date: Sat Jun 11 00:20:23 2022 +0200 s390/archrandom: simplify back to earlier design and initialize earlier BugLink: https://bugs.launchpad.net/bugs/1989625 commit e4f74400308cb8abde5fdc9cad609c2aba32110c upstream. ... because that's the only patch which has changes in the s390 start kernel/arch/random areas. ------- Comment From fre...@de.ibm.com 2022-10-26 11:15 EDT------- Recreate is totally simple: just install a Ubuntu 18.04 - does not matter if it is on LPAR or zVM or as a KVM guest. If my suggestion is right, this happens since kernel 4.15.0-194. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1994601 Title: [UBUNTU 18.04] Ubuntu 18.04 crashes during IPL Status in Ubuntu on IBM z Systems: Incomplete Status in linux package in Ubuntu: Confirmed Bug description: ---Problem Description--- Ubuntu 18.04 crashes during IPL with no output on the console.

It is not an issue with z14 but z17 also fails to run a fresh installed ubuntu 18.04. == Comment: #8 - Harald Freudenberger <fre...@de.ibm.com> - 2022-10-26 08:25:52 == when I use the 'advanced installation' where I am able to choose the kernel package and then choose the 4.15.0-50 generic the installed Ubuntu 18.04 comes up fine. So this issue is somewhere between kernel 4.15.0-50 and 4.15.0-194.
