Hello,
on both my ppc32 systems I've tested (G4 PowerMac and G4 Mac-mini), I
see a regression after upgrading from 4.14.74 to 4.14.76: Very soon
after starting the kernel from yaboot, they drop me into a OF prompt,
message is "invalid memory access at" on the mini, and another one I
forgot on the PowerMac. FWIW, the ppc64 G5 PowerMac does fine.
Before I start bisecting - might take a few days -, is this already on
radar?
Christoph

I have not heard of this, sorry.
Does the latest 4.18.y and/or the latest 4.19-rc8 release have this same
problem for you?
thanks,

FWIW, both systems are back to normal in 4.14.78 - as there have been
changes in the powerpc area, they probably did the right thing. And
while it was an interesting project to dig further, I afraid I lack the
time to actually do this.
Thanks for your attention in that matter.
