https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=233863 --- Comment #44 from Mark Millard <[email protected]> --- Another solid powerpc64 FreeBSD incompatibility for the PowerMac G5's is the following, not directly addressed by any of the attachments, but a working and in-use usefdt mode does avoid the problem. (So it is indirectly addressed to some extent.) When the "direct map" to high memory addresses, parts of openfimware and FreeBSD became solidly, reliably incompatible, leading to reproducible crashes. Unless you want the powerpc64 FreeBSD to crash, one thing to avoid is significant use of openfirmware, such as via use of ofwdump, say ofwdump -ap > /dev/null . When I wanted to use ofwdump, I booted 32-bit powerpc FreeBSD on the G5 instead and use ofwdump from there. (This was before I could put usefdt mode to use. Now I've two types of contexts from which I can run ofwdump without crashing.) -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-ppc To unsubscribe, send any mail to "[email protected]"
