Hi,
I had this problem with kernel 4.5 where the kernel would crash in kernel
mode with trap 12.
Kernel 4.3 worked fine.
Now I KNOW that the fix for this is to set hw.pcic.intr_path="1" and
hw.pcic.irq="0" and it works fine!!!
Though I want to know if this will be fixed in upcoming kernel versions so
that there is no need to set these variables?
here is the kernel output:
----------------------------------------
pci0: <unkown card> (vendor=0x1039, dev=0x7018) at 1.4 irq 5
pci0: <unkown card> (vendor=0x1039, dev=0x7013) at 1.6 irq 10
pcib2: <PCI to PCI bridge (vendor=1039 device=0001)> at device 2.0 on pci0
pci1: <PCI bus> on pcib2
pci1: <SiS model 6300 VGA-compatible display device> at 0.0
pci_cfgintr_virgin: using routable interrupt 3
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xeb902
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc00eb807
stack pointer = 0x10:0xc035ed6c
frame pointer = 0x10:0xc035ed6c
code segment = base 0x0, limit 0xfffff, type 0x1b

processor eflags = interrupt enabled, resume, IOPL=0
current process = 0 (swapper)
interrupt mask = net tty bio cam
trap number = 12
panic: page fault
Uptime: 0s
----------------------------------------
I KNOW THE FIX ALREADY!! Just asking if this will be fixed in upcoming
kernel versions!
Currently it looks more like a workaround than a real fix.
Posting in -mobile because it happened to my notebook (Gericom Overdose,
SiS630 chipset, Celeron 1000Mhz, 256MB RAM).
Sincerely,
Andreas
