State Changed From-To: open->feedback Can you please retry with 5.1-RELEASE or 5.1-CURRENT? Responsible Changed From-To: freebsd-bugs->acpi-jp@jp.FreeBSD.org Assign to ACPI maintainers State Changed From-To: feedback->closed Resubmit if you still have the problem with 5.1-current. Since this is a desktop, an acceptable workaround is: echo "hint.acpi.0.disabled=1" >> /boot/loader.conf |
How-To-Repeat: I just installed the FreeBSD 5.0-RC1 from a floopy and FTP site. When booting from the floppy showed a message like "acpi.ko module load failed", but I proceeded with the installation. The install proceeded normally, but, when booting the kernel installed, this fault happened: ... real memory = 3742269440 (3568 MB) avail memory = 3638677504 (3470 MB) Initializing GEOMetry subsystem Pentium Pro MTRR support enabled npx0: <math processor> on motherboard npx0: INT 16 interface acpi0: <IBM SERCRSDR> on motherboard ACPI-0625: *** Info: GPE Block0 defined as GPE0 to GPE31 Fatal trap 12: page fault while in kernel mode fault virtual address = 0xcacacaca fault code = supervisor read, page not present instruction pointer = 0x8:0xc0684bd0 stack pointer = 0x10:0xc06d797c frame pointer = 0x10:0xc06d7994 code segment = base rx0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 0 (swapper) kernel: type 12 trap, code =0 Stopped at AcpiNsAttachObject+0x70: cmpb $0xaa,0(%ebx) To boot the system, I needed to disable the acpi module with unset acpi_load but this is not so much useful for a SMP system :-)
