Hello,
I'm trying to get a Gateway laptop working on CURRENT. See dmesg.txt for
hardware details. Also notice the lock order reversal complaint, but it's
not my main problem. The main problem is that it crashes quite often. It
always crashes in one of the acpi threads, but not always in the same.
I've seen it happen in both acpi_task? and in acpi_thermal. I can run for
quite a long time, but eventually it happens. The most reliable way to
provoke crash is to start buildworld. As a result I'm running with
5.0-RELEASE system and 5.1-BETA kernel (took arount 10 attempts to build
the kernel). Now when it crashes I get into debugger, but I couldn't
figure out how to make it dump core. I tried givin 'panic' command and it
seemed like it was dumping core, but it's not in /var/crash. Am I doing it
wrong?
Anyway, here is the trace (typed it in manually):
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x80790ab0
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc06ea4d0
stack pointer = 0x10:0xcd10bbf0
frame pointer = 0x19:0xcd10bbf0
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 6 (acpi_task1)
kernel: type 12 trap, code=0
Stopped at AcpiNsMapHandleToNode+0x20: cmpb $0xaa,0(%edx)
trace:
AcpiNsMapHandleToNode

acpi_pwer_switch_consumer
acpi_tz_switch_cooler_on
acpi_ForeachPackageObject
acpi_tz_monitor
atcpi_task_thread
fork_exit
fork_trampoline
Please excuse me if this is wrong place to send this and thanks in avance!
