hello,
when I compile in atapicam in my kernel (with or without CAMDEBUG)
I get :
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xff00ff2c
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc0442720
stack pointer = 0x10:0xc0c21bbc
frame pointer = 0x10:0xc0c21bbc
code segment = base 0x0, limit 0xfffff, type 0x1b

processor eflags = interrupt enabled, resume, IOPL = 0
current process = 0 (swapper)
kernel: type 12 trap, code=0

For info, please find attached :
atapicam.dmesg (a bit cut-off, I just have an old win98 box
with hyperterminal to server as serial console)
std.dmesg (same KERNCONF, recompiled without atapicam;
KERNCONF basically is GENERIC, unneeded drivers commented out,
SCHED_4BSD,HZ=1000 and acpi compiled into the kernel)
Regards, Arno
