This one happened on my second mirabox, with the same kernel as my last
problem
(see "Undefined instruction (ldrshtgt?) on mirabox with 3.11-rc7"
thread); I'm hoping
there's not some general (overheating?) hw problem with these boxes.

A "prefetch abort" means that the CPU was unable to fetch the instruction
for some reason. The address of the instruction is 0xc014aae8, and the
reason is "section domain fault" - this means that the CPU thinks the
section mapping specified a domain number which denied it access to this
mapping (in other words, the domain associated with this mapping was set
to "no access").
There's two strong arguments against that being the case though:
1. The oops code can read the data located there; domains have no separation
of read vs execute permission, and the CPU was in the same mode as it is
when it dumped this oops. So the domain is accessible, even though the
abort indicated it was not.
2. The CPU executed the two preceding instructions from this code before
spitting out this error. Again, this indicates that the domain was
accessible immediately before this abort was raised.
This is also inside __memzero, which will have been used many times before
this point, so its highly unlikely that the kernel would have been booted
if there was a problem here.
so, i'm afraid again, I don't think this is a kernel bug but pointing
towards a hardware weakness. The argument against that is you say that
it's a different (your second) mirabox... unless it's a generic design
weakness.
Keep on posting the oopses though, there may be a pattern to them.

I was afraid you were gonna say that :/

Globalscale's somewhat infamous for heat issues with the Guruplug ; the
mirabox is supposed
to not have the issue, and I don't immediately see any reports of it,
but it wouldn't totally
surprise me. The boxes are fairly hot to the touch (It won't burn your
finger but it definitely
gets uncomfortable), and that's in a basement where the ambient temp
probably never goes
above 75f.
>>> Keep on posting the oopses though, there may be a pattern to them.
Another clue in the heat direction might be that with the rain the last
few days things seem
at least a bit better, though it's probably too early to draw
conclusions. First box's been up
for 2 days 10 hours now, and the with this oops above 18 hours.
Thanks for looking again.

Sorry if those questions have already been posted in the previous
thread. What kind of tests / workload are you running on your Mirabox
to trigger the crash? I might be able to get one or two Mirabox running
here, so I could see if the problem is reproducible.
Also, is this something you're seeing only since 3.11-rc7 ? Is the
kernel originally provided with the Mirabox more stable ? Are earlier
kernel versions (such as 3.10 or earlier) more stable ?
Thanks,
Thomas

Nothing too fancy. They're running a corosync/pacemaker cluster with
apache, bind,
openvpn, dovecot, postfix and mysql, all for personal use only, so a
fairly light load.
CPU idle generally hovers just below 80%.
That said, I think at least one of the oopses happened while I was
updating the kernel;
IIRC it happened either during the git pull or make clean though, not
during the actual
make.

Things get a bit murky here.
I did not get any problems with the included (with the marvell patches)
2.6.35, but I didn't
run it all that long since I don't like debian and it didn't work with a
recent fedora because
of systemd. I was running that kernel + a cgroup patch for quite a
while without any issues.
A stock 3.10 kernel compiled on fedora 18 has been working without any
issues for at least
a month. That exact same kernel and exact same config compiled on
fedora 19 results in an
oops shortly after boot however. (First oops below)
3.11-rc3 compiled on FC19 results in another oops (second one below);
compiled on FC18
I initially thought it worked fine but I think it eventually oopsed as
well (didn't save it, sorry),
so I went back to my 3.10 kernel.
And my current 3.11-rc7 is the next one I tried. I don't have a FC18 box
anymore so kernel is
compiled on FC19 (directly on the mirabox).
One other thing with the stock kernels is that the network interfaces
will not work properly
unless they're activated from u-boot, i.e. if I just do an sdcard boot
the interfaces will show
up and appear ok but won't actually send/receive any data. Simply doing
a "dhcp ; setact
egiga1 ; dhcp" before continuing the boot makes them work fine. This
wasn't a problem with
the original kernel.

Next ones. Box had been running without issues for a few days on 3.11
+ Thomas'
patch for the HW PHY polling.
Recompiled the kernel with Willy's patches for the atags MAC passing,
then got the
three OOPSES below during the reboot; I was still able to log in, just
rebooted again,
and this time it came up without any issues.
There's one weird timing thing I don't quite understand as well;
probably unrelated but I
thought I'd mention it anyway. The failing boot was a simple "reboot"
command, and
showed this:
[ 0.000000] Aurora cache controller enabled

The 39 seconds is probably about right from the start of u-boot till
this point. In the working boot
afterwards, which was a full powercycle (networked PDU), it shows:
[ 0.000000] Aurora cache controller enabled

Don't know where the big difference comes from, or how it gets to 223
seconds there.
