Comment 1 Josh Boyer 2012-08-27 09:06:38 EDT
You had a single bit flip in memory.  That can often be a sign of a memory module failing.  I would suggest running memtest86+ overnight and seeing if you get any errors.
Comment 2 Need Real Name 2012-08-30 13:56:30 EDT
I understand this does not prove anything,
but after 32 hours of continuous memtestx86 v4.20
no single memory error found
Comment 3 Josh Boyer 2013-03-14 13:50:05 EDT
Are you still having issues with this with 3.8.2 in updates-testing?
Comment 4 Need Real Name 2013-03-15 10:05:58 EDT
I did see this issue only once.
No repeat.
1 week of continuous memtestx86 v4.20 did show nothing.

I understand this 1 bit flip-flop can be anything
from kernel bug to a cosmic gamma quant.

The memory/motherboard has no ECC memory check.
Comment 5 Josh Boyer 2013-03-15 10:11:33 EDT
OK, we'll close this out for now.  If you see it again, please reopen.
