Comment 1 Dave Jones 2012-07-10 21:47:54 UTC

can you reproduce this in 3.4 ?

Comment 2 Bas Hulsken 2012-07-11 07:37:49 UTC

(In reply to comment #1)
> can you reproduce this in 3.4 ?

Nope, I haven't. This bug should be invalidated, the report is unreliable. I'm quite certain it was caused by a faulty memory module. I've taken out the defective module (with the help of memtest86), and haven't had any problems for the last two days on 3.4. Even when simulating heavy I/O load, which would trigger the bug previously. Haven't tested 3.3 again though.

apologies for the noise

Thanks for letting us know.
