Greetings,
My first post to this mailing list...
I do not KNOW that this belongs here. I am posting here because I
have in the past used the kernel implementation of the qcam drivers
without the problems that I will described below. Since I just
became current with stable, it seemed that this is a good place to
start with my problem. Please direct me to the proper venue if my
plea for help does not belong here.
Two nights ago I brought myself current to -current with cvsup.
After updating my sources, I performed a make world and compiled
myself a new GENERIC kernel.
After I felt safe with this, I started tweaking. The first step
was removing all unused network, scsi and hd drivers from a copy of
GENERIC. No problems.
Next... I commented out the lpt0 driver and added the following
for qcam0:
#device lpt0 at isa? port? tty irq 7 vector lptintr
device qcam0 at isa? port "IO_LPT1"
Everything SEEMED to be fine. Until I ran /stand/sysinstall, the
following error was displayed:
Dec 15 00:28:28 amber /kernel: stray irq 7
OK, I modified the qcam0 device to snag irq 7 in the same manner
that was used for the now disabled lpt0:
device qcam0 at isa? port "IO_LPT1" tty irq 7
Now, when I try to run sysinstall, the following is displayed as the
system crashes:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:0x0
stack pointer = 0x10:0xefbffe20
frame pointer = 0x10:0xefbffe78
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 = 203 (sysinstall)
interrupt mask = net tty
panic: page fault
Any help is appreciated!
