Public bug reported: Currently, zfcpdump-kernel in ubuntu is on-par with v4.9 sources, and it does successfully complete SCSI dump of Ubuntu 17.10 which itself uses v4.13.
Our kernel team has attempted to upgrade zfcpdump-kernel to v4.13 sources, however such a kernel fails to complete the SCSI dump. (see attached operating systems messages) With v4.9 based zfcpdump-kernel the kernel dmesg are cleared very quickly, and zfcpdump programme starts executing from the zfcpdump initrd pretty much instantly. You can check v4.13 build-log & package at https://launchpad.net /~canonical-kernel-team/+archive/ubuntu/bootstrap/+build/13538881 Direct URL to download the v4.13 zfcpdump-kernel is: $ wget https://launchpad.net/~canonical-kernel-team/+archive/ubuntu/bootstrap/+build/13538881/+files/zfcpdump-kernel_4.13-0ubuntu1~rc2_s390x.deb $ apt install ./zfcpdump-kernel_4.13-0ubuntu1~rc2_s390x.deb After that use zipl to prepare a drive for a dump as usual, and perform the dump. We have also tried v4.10 based on zesty (17.04) release, compiled with zesty toolchain, and similar failure was observed. Are there any new measure that we should be taking to configure, compile, and successfully create a zfcpdump compatible kernel, based on upstream v4.10 or later kernels? ** Affects: zfcpdump-kernel (Ubuntu) Importance: Undecided Status: New ** Tags: s390x ** Attachment added: "operating-system-messages-v4.13-kernel-zfcpdump.pdf" https://bugs.launchpad.net/bugs/1722735/+attachment/4967394/+files/operating-system-messages-v4.13-kernel-zfcpdump.pdf -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1722735 Title: zfcpdump-kernels later than v4.9 fail to boot / fail to find initramfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zfcpdump-kernel/+bug/1722735/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
