--Apple-Mail-D01F56F1-9589-459D-B003-E6AD98A2D654 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit I have had pretty much the same thing going on on my PowerMac G5 after 11.0-BETA3 for more than a month now with every single snapshot I have tried. The latest snapshot I have tried was r305652 of today. BETA2 still boots just fine. If you have seen this also in 10.2-stable, it means someone has commited something which was not properly tested on all supported archtectures, though, it affects those untested architectures, and then been backporting a dysfunctional commit also to older stable releases instead of backing the change out of the source tree until the problem has been properly fixed. As a side effect I will no longer dare to build a new snapshot on my G4 (ppc, 32-bit) either. It has been running 10.3-stable which might also be affected, if 10.2 is affected. The story apparently goes such that the interrupt code shown can be pretty much anything. The interrupts might simply be enabled way before the system is ready to handle them. --jau --Apple-Mail-D01F56F1-9589-459D-B003-E6AD98A2D654 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: quoted-printable > On 09 Sep 2016, at 02:55, Krzysztof Parzyszek <kristof@swissmail.org> wrot= e: >=20 > Hi, > I'm having trouble getting FreeBSD stable/11 to work on my G5.
