Created attachment 1160417 [details] Patch to remove check as done on arm64 Description of problem: 64K page-table size check fails for 4K powerpc machines. This causes polkitd to fail.
...and polkitd failing causes all kinds of other major problems. The severity should be bumped above medium. This basically makes it so you can't start a service from the command line on powerpc.
I can confirm that the attached patch fully resolves the problem for me. Thanks, Ed!
it's fixed in mozjs17-17.0.0-19.fc27 built in rawhide. Thanks
