Hello,
I'm trying to use graid3 to create a raid volume from three
250GB SATA discs. I can successfully label, format, and mount
the disc. The problem arises when I try and migrate some data
on to the new volume. I'm using rsync to do this from over the
local network, unfortunately this seems to be produce an
immediate and reproduceable panic (hand copied):
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0xc30f8000
fault code = supervisor write, page not present
instruction pointer = 0x8:0xc05e9783
stack pointer = 0x10:0xd8030c38
frame pointer = 0x10:0xd8030c80
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 = 617 (g_raid3 raid)
trap number = 12
panic: page fault
Other programs (touch, ls, diskinfo, etc) do not seem to provoke
the panic, but rsync will kill the system within a second.
I got a dump (once), but I think it is corrupt in some way
because I have not been able to get a backtrace or any other
useful data from it.
# kgdb kernel.debug /usr/crash/vmcore.0
kgdb: kvm_read: invalid address (f9)
(This line is printed again, and again, and again ...)
This may be because I compiled my debugging kernel after I had
installed the system, although it should have been an identical
source tree ... I'm currently rebuilding the system to
the freshest available -STABLE in the hope that may give a
full backtrace.

The only thing slightly odd about the machine is that each
disc is one its own SATA controller. One disc is attached to an
Intel ICH6 the other two are attached two Silicon Image (3112)
based cards. The root device is ad2, since the additional cards
have pushed themselves to the front. This is a temporary setup
to facilitate migration of data from system to system.
If I can do anything to help track the problem down, please say.
I really want this to work, and I have some time in which to run
tests.
* A side note, I have noticed that the panic is often accompanied by
a ATA DMA timeout (ad1). Could this cause the panic to occur?
