Just because Memtest86 went 30% without failure does not mean your RAM is 30% OK. It should run for at least a full loop, and I typically run it for at least 2 loops (though only once have I seen a system suddenly start spewing errors it didn't have during the first loop, and I've run it on a lot of systems). It does take a while, so you probably don't want to sit around watching it. I usually let it run overnight while I sleep. |

Ok, so I compiled a new kernel, and it seemed to work. I booted the new kernel, I was able to unzip and install dhcpcd, ndiswrapper, wireless-tools, and cab extract. Then, once the wireless was working, I tried emerge --search dhcpcd, because gentoo apparently doesn't like my manually configured dhcpcd.... CRASH! I ran memtest86+, as suggested, and it got to at least 30% without a failure. I'll try it again, but at least 30% of my memory is in tact. I'll try to emerge some other things, and see how it goes. |

Any new laptop should have the hardware smarts not to smoke itself, or |
30 |
something really is broken. It may shut down "unexpectedly" (which I |
31 |
also consider a design bug), but actually causing damage is unlikely. |
32 |
|
33 |
|
34 |
That said, this really sounds like a RAM problem, so I would run |
35 |
memtest86 first. Memtest86 has zero chance of smoking any system that |
36 |
has passed a factory QA check. |

I had a Gentoo system (a server) that pretty much ran (to be honest, it |
39 |
|
40 |
was a heavily used database server that stayed up for a good 3 months in |
41 |
this state). However, its clock was skewed something like 10m/hour (I |
42 |
now think this was due to lost ticks during processing of memory |
43 |
|
44 |
faults). |
45 |
|
46 |
I tried all the various kernel flags, largemem, etc., only to find out |
47 |
that the problem was (as others on this thread have posted) incompatible |
48 |
RAM. I point this out only to say that bad RAM can cause *very* unusual |
49 |
|
50 |
problems (not just the segfaults you'd expect), and to say that lots of |
51 |
complex operations (like Vista, for example) can continue to run just |
52 |
fine in such a broken environment. |
