Uhhuh. NMI received for unknown reason b1 on CPU 0.
You probably have a hardware problem with your RAM chips

Jeff Burke cannot reproduce this issue.


Comment 8 Don Zickus 2008-03-24 10:20:23 EDT
Well NOTABUG is not true.  This is a bug.  Just not in the software but probably
the hardware.  In fact it is probably transient which is why people can't
reproduce it.  I mean corrupted memory bits only happen once in a blue moon, so
unless you test this a billion times a row you may never reproduce this problem.  

The odd thing about this problem is that EDAC should have diagnosed and possibly
fixed this issue (that's the whole reason for its existence is to catch/handle
the memory problems).  Perhaps that is where the software bug is.  

I'll talk to Aris about this.  But unfortunately I don't expect much to come out
of it.  

Cai, please continue to file these types of reports because problems like this
are trappable by the kernel and should be recoverable too, I think.

Comment 9 Prarit Bhargava 2008-03-24 10:33:14 EDT
Really this should have been closed as INSUFFICIENT_DATA -- I was being lazy ;)

Comment 11 Tony Camuso 2008-03-24 11:05:45 EDT
Please try re-seating the memory DIMMs.

This system was working fine when I installed it and for at least a few days

I don't think the different kernel versions matter as much as what may be an
intermittent contact on the DIMMs or even a flakey DIMM.
