RE: [gentoo-user] possible defective memory
FWIW, I had the same problem, (compile would hang, no error, no message, nothing), while installing a dual AMD64 system last week. I got past it by using kernel switches to force single CPU (nosmp), and disabling the apic (noapic), during the install. Don't know for sure which switch resolved it, or if they were both needed. May not help you, but thought I'd mention it just in case.

[gentoo-user] possible defective memory
I've got 2 sticks of Kingston HyperX 3200 DDR Registered ECC. Is it possible that this if I ran memtest86+ for 2 days straight and found no error that the memory could still be defective? I ask because I can't get a complete compile of glibc. I have to restart the process at lease 3 times before the compile will complete. Let me know what you think. -- bruce -- gentoo-user@gentoo.org mailing list

Changed PSU, glibc compiled just fine. This was on an MSI MB with an AMD 750 Duron. I had 4 PSUs so far going weak - sometimes the box only booted after the nth try, sometimes it suddenly crashed, segfaults and so on. Almost everything that you could also blame on faulty memory or bad cooling. That's why I always blame the PSU first, if it is not a quality brand one ;) I have an enermax for more than a year now (should be almost two, if I remember correctly) since then, all this problems vanished. I friend brought a PSU which had a defect - I started it - boom it exploded.. for the second time, we learnt, after disecting it ;) Another one killed his PSU, when he connected a big old scsi-drive - burned capacitors and transistors don't smell nice -- gentoo-user@gentoo.org mailing list

I had exactly the same problem when I assembling together AMD64. It took me one week to investigate. Memorytest86 pass all the test and the system was still crashing when I was compiling for a longer time. So in other words Memorytest86 it is not worth the disk space it occupies. Look on Google for another test called: memtest.sh from RedHat and run it. In my case it was memory issue. I got a new pair of stick and the problem went away. -- #Joseph -- gentoo-user@gentoo.org mailing list
