#6319: Problem with multi core CPU -------------------------+------------------------------------------------- Reporter: Miroslav- | Owner: nobody Stimac | Status: closed Type: bug | Milestone: R1 Priority: normal | Version: R1/alpha2 Component: - General | Keywords: multi core cpu, alpha 2, Resolution: fixed | installation, problem Blocked By: | Blocking: Has a Patch: 0 | Platform: x86 -------------------------+------------------------------------------------- Comment (by Miroslav-Stimac): Hello, I downloaded the R1 Alpha 3 CD Image and tried to install in on my notebook. Now I have the same problem as I reported about one year ago in this ticket. I still have the same hardware. What did happen? Why does the Alpha 3 not work with both cores on my notebook? Had been the old bug reimplemented? ;-) On my notebook I have an older version installed: Haiku GCC4 Hybrid, Revision 39771. Dual core works without any problems with this old version! I know that my notebook has problems with Haiku regarding ACPI or APM and therefore I disable them. But Haiku still fails to boot if I do not disable the dual core support in the BIOS. Disabling any other features in the boot menu does not help. Usinf fail safe mode or fail safe video resolution has no effect, too. The problem seems to be exactly the same one as the one that I described in the ticket. Therefore I would recommend to reopen it. Best wishes, Miroslav Stimac P.S.: I tried the latest nightly builds: haiku-nightly-r41539-x86gcc4hybrid- cd.tar.xz and haiku-nightly-r41539-x86gcc2hybrid-cd.tar.xz ==> The same problem. I will test older versions, but this will take some time. It is midnight now, so I will have to go to bed. :-) -- Ticket URL: <http://dev.haiku-os.org/ticket/6319#comment:12> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
