Well, what a week! I ran two copies of this useful script, one on each |
9 |
physical disk [1], while simultaneously running BOINC clients at nice=19 |
10 |
to fill in the CPU gaps. Sometimes I would try an emerge -e world |
11 |
instead of one of the memtest scripts; I did that because I wasn't sure |
12 |
I'd cleaned up the tool-chain since installing, so I emerged |
13 |
linux-headers, glibc, binutils and gcc and then -e world. |
14 |
|
15 |
I still kept getting segmentation faults, and other compilation errors |
16 |
occurred in a few packages such as xorg-x11. Each segmentation fault |
17 |
disappeared on running emerge --resume, as expected. Eventually I |
18 |
remembered revdep-rebuild; running that cured the xorg-x11 problem (I |
19 |
forget which library was rebuilt). The memtest script passed every time |
20 |
- and the disk temperatures rose anything up to 20 C to over 50 C, which |
21 |
illustrates the amount of extra work they were doing. |
22 |
|
23 |
So I have a box that passes all tests except one: compiling programs. |
24 |
Looks like I'll just have to wait for a harder fault to appear. Thanks |
25 |
to all who've offered suggestions. |

[1] I did notice one minor wrinkle. The two copies started in series, so |
34 |
one was always following the other with its requests for disk transfers, |
35 |
at least at first, and so fell steadily behind. But by specifying, say, |
36 |
40 passes, I saw that the two instances eventually drifted well out of |
37 |
sync; I deduce therefore that the occurrence of interrupts will have |
38 |
been random for all practical purposes. Secondly, I used a kernel |
39 |
without swap because I thought it would make no difference; the disks |
40 |
were being stressed equally anyway. Thirdly, I ran some tests from |
41 |
xterms, and others from the console without X running. |
