Tl;dr--Installation successful; Nvidia was the culprit. Follow up:
*Attempt n *(some large number)*:* Disabled SpeedStep. Passwords quickly entered. Cursor lag 819/1025. Cursor freeze 836/1025. "DNF error: Error unpacking rpm package anaconda-core-1000:25.20.9-16.fc25.x86_64". *Attempt n+1:* Kept SpeedStep disabled. Booted ANACONDA. Passwords quickly entered. Cursor lag ~830/1025. Cursor freeze 840/1025. "DNF error: Error unpacking rpm package gtk3-3.22.17-2.fc25.x86_64". *Attempt n+2:* Kept SpeedStep disabled. Disabled C-State Control. Passwords quickly set. Cursor lag 808/1025. Cursor freeze 812/1025. *Installation proceeds*. At 839/1025: "DNF error: Error unpacking rpm package adwaita-icon-theme3.22.0-1.fc25.noarch" *Attempt n+3:* Same setup as before, but didn't set languages or time. Didn't set passwords. Complete freeze 809/1025. CPU fans at max for 5 mins before hard reset. Hard doubts about approach. *Attempt n+4:* Re-enabled SpeedStep and C-State Control. Edited BOOTX64.cfg to add "nouveau.modeset=0" param to kernel config keys. Booted ANACONDA. Passwords quickly set. Installation succeeded. Nvidia was the culprit here (no option to disable in BIOS). Installation booted, configured, and setup without issues--thanks for the great start to a new decade! * Will definitely see some of you around here as I poke around. **Yes, I know it's technically not the start of a new decade.* -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
