Hi agian,=20

I have written to this group a couple of time concerning my system do a =
lot of strange=20
crashing. The replies I have gotten back have been helpful and have =
tried to point the blame
at either XFree86 4.0 or maybe a hardware problem. Both of these seemed =
like likely causes
and because I could not identify anything specific as to when or what =
would cause a crash, I let it
be and continued to watch these crashes to see if anything turned up. =
In addition I ran quite a few
diagositc test on the hardware (using harddrive manufactor testing =
software, wintune98, passmark-burnin
test, etc. And could not find any problems with the hardware -- well, =
that's not totally true, but I will get=20
there).

What has prompted me to write again (and hopefully not be thought to =
much of a fool) is that I have seen a=20
series of kernel panic's of which I actually saw some output (most of =
the time the system just locks-up and I don't get anything). In three =
diffrernt cases I got the following error prior to a kernel panic

mapaddr 0x74c881d4 not valid at usb-ohci.c:1397

The address is the only thing that would change between the 3 cases. =
The things I was doing when I got this message - running memtest =
(checking out the memory), compiling the kernel (2.4.0-test1), and =
booting up the=20
new kernel.

Now I realize that recreating these panic's would be nearly impossible - =
it does seem to point to something
in the kernel being wrong. BTW - in all three instances I was running =
without XFree.

If I need to add anything or try anything to help solve this problem, =
please don't hesitate to ask.
