Can't boot 8/CURRENT hvm on Quad-Core Opteron 2352
Hi, I'm trying to run a FreeBSD 8/CURRENT hvm on XEN, but booting FreeBSD currently panics on a quad-core Operton 2352 box while booting from the iso (disabling ACPI doesn't help). However, I'm successful at running a FreeBSD 8/CURRENT hvm on XEN on a Intel Xeon Nehalem box. I tried booting the same installed disk image (from the Nehalem box) on the Operteron box, but that also resulted in a panic while booting. The CURRENT iso I'm using is from: ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/201001/FreeBSD-9.0-CURRENT-201001-amd64-bootonly.iso I'm using Xen-3.3.1 on both physical boxes, and a BSD 6 hvm works on both the Nehalem and Operton boxes... Here's the backtrace from the opteron box: kernel trap 9 with interrupts disabled Fatal trap 9: general protection fault while in kernel mode cpuid = 0; apic id = 00 instruction pointer = 0x20:0x80878193 stack pointer = 0x28:0x81044bb0 frame pointer = 0x28:0x81044bc0 code segment= base 0x0, limit 0xf, type 0x1b = DPL 0, pres 1, long 1, def32 0, gran 1 processor eflags= resume, IOPL = 0 current process = 0 () [thread pid 0 tid 0 ] Stopped at pmap_invalidate_cache_range+0x43: clflushl(%rdi) db bt bt Tracing pid 0 tid 0 td 0x80c51fc0 pmap_invalidate_cache_range() at pmap_invalidate_cache_range+0x43 pmap_change_attr_locked() at pmap_change_attr_locked+0x368 pmap_change_attr() at pmap_change_attr+0x43 pmap_mapdev_attr() at pmap_mapdev_attr+0x112 lapic_init() at lapic_init+0x29 madt_setup_local() at madt_setup_local+0x26 apic_setup_local() at apic_setup_local+0x13 mi_startup() at mi_startup+0x59 btext() at btext+0x2c I took a look through the bug database and didn't see any similar problem reports.
