drop-back to
Fedora (5.12.15-300.fc34.x86_64) 34 (Thirty Four)
boots, again, with no issues.
for the
Fedora (5.13.4-200.fc34.x86_64) 34 (Thirty Four)
case, with logging dialed up,
logs show a sloooooow boot process ( 700+ seconds and counting ), with eventual, complete hang @
"Starting Apply Kernel Variables..."
--> https://pastebin.com/dP6Lm84J
So far, this occurs on this J1900 box only; other-hardware F34 installs with kernel >= 5.12.17 are booting fine.
AND, for _this_ J1900, all kernels <= 5.12.15 boot OK.
if there's specific, additional logging that'd be informative, I can attach. or, redirect to other list.
