https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D226365 Bug ID: 226365 Summary: ppc64: Loader: Unable to load two kernels Product: Base System Version: CURRENT Hardware: powerpc OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: breno.leitao@gmail.com I am not able to load two kernels in the loader. If I want to load a newer kernel, I need to unload the first one, otherwise it gets in the OFW trap.

We should, either, ask for more memory for the newer kerne= l, or, reuse the same memory as used in the first kernel. --=20 You are receiving this mail because: You are the assignee for the bug.=
