Package: src:linux
Version: 3.16.7-ckt11-1
Severity: important

Dear Maintainer,

The following kernel panic error appears at random in Xen virtualisation.
Please look at the error in screenshot attachment.
It's a Debian 8, Kernel 3.16.7-ckt11-1+deb8u5, Xen 4.4.4-pre
It's a production machine so not much detailed further testing can be provided in time.
The information below (bugreport) is executed from a different machine, so the info provided below is not matching the original machine where the error appears !

Kind regards,
Jan

Thanks for your report.

Package: src:linux
Version: 3.16.7-ckt11-1
From your text and the screenshot I think this should really be
+deb8u5. I've updated the bug metadata with the first lines.

Severity: important
Dear Maintainer,
The following kernel panic error appears at random in Xen
virtualisation.
As in it has appeared randomly from time to time (i.e. more than once)
or you've had a single random instance?
Post by Jan Prunk
Please look at the error in screenshot attachment.
It's a Debian 8, Kernel 3.16.7-ckt11-1+deb8u5, Xen 4.4.4-pre
The screenshot shows a fault at 0xffffffff812b6dad == memcpy+0xd,
called from ndisc_send_redirect+0x3bf.

Unfortunately disassembling memcpy from what I think is the correct dbg
package[0] results in:

Dump of assembler code for function memcpy:
   0xffffffff812b6da0 <+0>: mov    %rdi,%rax
   0xffffffff812b6da3 <+3>: cmp    $0x20,%rdx
   0xffffffff812b6da7 <+7>: jb     0xffffffff812b6e27
<memcpy+135>
   0xffffffff812b6da9 <+9>: cmp    %dil,%sil
   0xffffffff812b6dac <+12>: jl     0xffffffff812b6de3
<memcpy+67>
   0xffffffff812b6dae <+14>: sub    $0x20,%rdx
   0xffffffff812b6db2 <+18>: sub    $0x20,%rdx

i.e. the faulting %rip (0xffffffff812b6dad) is not on an instruction
boundary (it would be in the middle of that jl instruction, which
cannot happen).

The call in ndisc_send_redirect disassembles sensibly and matches up
ok.

If I decode the faulting address as if it were on an instruction
boundary then I get:

(gdb) x/i 0xffffffff812b6dad
   0xffffffff812b6dad <memcpy+13>: xor    $0x20ea8348,%eax

which isn't accessing RAM and therefore surely cannot fault.

The version you have given is corroborated by the screenshot and I am
pretty I have got the correct dbg package to match.

I suppose you haven't rebuilt the kernel or anything like that?

I don't like to put things down to "cosmic rays", but if this was a one
off then I'm struggling to think of anything else to explain what
appears to be a single bit error in %rip.

At this point I would normally ask if you had run memtest86 etc on the
machine (i.e. if the RAM is known to be solid), but this seems to be a
register and not memory related.

It's a production machine so not much detailed further testing can be provided in time.
The information below (bugreport) is executed from a different
machine, so the info provided below is not matching the original
machine where the error appears !
FYI it is possible to run reportbug on a machine but get it to write
the report to a file for transfer and sending from another machine.

Ian.
