* I added this bug as blocker for f26 Alpha for PowerPC bug #1430827 * Do we keep this bug open ? or is it same problem as already tracked by https://bugzilla.redhat.com/show_bug.cgi?id=1411321 related to redhat 7.3 and rescue mode. The problem is still present with the Alpha-1.7 ISOs. But playing with the compression of the initrd.img file embedded in the ppc64le ISO, I was able to boot on a LPAR and perform the installation. Initial initrd.img file size: 48663908 bytes Re-compressed file size: 44875647 bytes, -7,78% (using the "xz -9e --format=lzma" command for compression) Maybe the compression of initrd.img could be tuned this way... until a more generic solution is provided (see bug #1411321). FYI, the patch of bug #1411321 is upstream as per related https://bugzilla.redhat.com/show_bug.cgi?id=1411321#c27 who is supposed to pull it for f26 ? I will a send a request to the fedora kernel list. Tested with the Fedora-Server-dvd-ppc64le-26-20170413.n.0.iso image. The problem still occurs with F26: ...

The kernel is loaded, the installer starts and installation with Anaconda using VNC ends successfully. After restart the new installed Fedora boots until the prompt, and we can log in the system. We want compose newer than Fedora-26-20170414.n.0, which should be the last with 4.11.0-0.rc5.git0.1.fc26.ppc64le kernel, the next will have kernel-4.11.0-0.rc6.git0.1.fc26 with the memory size fix. I confirm Fedora-26-20170420.n.0 ppc64 and ppc64le isos with new kernel-4.11.0-0.rc6.git0.1.fc26 boot without any problem on LPAR now. Thanks for verifying. |
