Subject: [BISECTED] kexec regression on PowerBook G4
Date: Wed, 22 May 2019 01:18:59 +0300 [thread overview]
Message-ID: <20190521221859.GC3621@darkstar.musicnaut.iki.fi> (raw)
Hi,
I was trying to upgrade from v5.0 -> v5.1 on PowerBook G4, but when trying
to kexec a kernel the system gets stuck (no errors seen on the console).
Bisected to: 93c4a162b014 ("powerpc/6xx: Store PGDIR physical address
in a SPRG"). This commit doesn't revert cleanly anymore but I tested
that the one before works OK.
With current Linus HEAD (9c7db5004280), it gets a bit further but still
doesn't work: now I get an error on the console after kexec "Starting
new kernel! ... Bye!":
kernel tried to execute exec-protected page (...) - exploit attempt?
A.
