MCE going wild, 14 megs of this in the logs

MCE going wild, 14 megs of this in the logs

[Gene Heskett]

Greetings;
Mar 30 16:46:42 coyote kernel: [469249.031832] MCE: The hardware reports a non 
fatal, correctable incident occurred on CPU 0.
Mar 30 16:46:42 coyote kernel: [469249.031838] Bank 1: d400400000000152
Mar 30 16:46:42 coyote kernel: [469249.031841] MCE: The hardware reports a non 
fatal, correctable incident occurred on CPU 0.
Mar 30 16:46:42 coyote kernel: [469249.031844] Bank 2: d40040000000017a

Its always the same 2 addresses reported, and every 15 seconds.  So I have the 
non-fatal part of MCE now turned off, & 2.6.24.4 rebuilding.

I saw this once before, and a nearly round the clock run of memtest86 gave my 
memory a clean bill.  Processor is an XP-2800, biostar mainboard with NForce2 
chipset.  Is this possibly a known artifact of this hardware?

Hi,

you possible have some buggy hardware. I'd suggest running this through 
mcelog, which should decode the MCE reason.

Thats expected. If ECC can correct the problem, memtest will pass.

I had similar problems, and was told by AMD that I had cpu with bad L2 cache.
