Attachment is from first 42.3 try. To reproduce: 1-fully GPT partition wiped target HD in advance 2-format all Linux native partitions in advance 3-boot netboot CD on new Kaby Lake PC configured to boot UEFI 4-proceed through "Custom Partitioning (for experts)" specifying existing but unformatted GPT /dev/sda1 ESP partition be formatted FAT32 for mount on /boot/esr 5-proceed through package selection 6-configure passwords 7-select booting from installation settings screen 8-select kernel parameters tab Actual behavior: 1-busy indicator stays on indefinitely 2-mouse clicks produce no response 3-top on tty2 shows 200% CPU from y2start Expected behavior: 1-able to proceed with and complete installation -- You are receiving this mail because: You are on the CC list for the bug.
