1 I have started noticing the following messages in the dmesg output (and
2 in the log-files) on my Gentoo rig:

21 I have been running memtest for some time (~100h) and have not gotten
22 any error message - so I am suspecting that this is a CPU problem. Am I
23 correct?
24
25 If it was just these error-messages I would not be that worried, but I
26 have started to get a lot of "hangers" on this rig when compiling larger
27 packages. Could there be a relation to the error-messages?
