Hi, I'm trying to run Fiasco.OC amd64 build on an Opteron 6100 magny-cours series (4-way-SMP, 12-cores-per-chip). When it boots it is as if the scheduling interrupt on the local APIC is not getting set up correctly. It also warns about some errata. It does boot with MP disabled, and RTC for the scheduling - not much use on a 48-core machine though ;-)
Hi, after some investigation it seems to be a problem in our ACPI code, so you could try the attached patch for the fiasco kernel. If it does not work, it should at least give some more verbose output at boot, something like:
