Has anybody tried building their Gentoo (~x86) system using NPTL, PIC
and SMP? I have a hyperthreaded P4 3.06 system and I run it using an
SMP (2.6.1) kernel. I rebuilt my system using NPTL and PIC and at first
things would go very quickly. However, every time I have tried this, at
some point a threaded process gets stuck (i.e. there were four perl
processes that could not be killed, even with -9) that make the system
essentially stop responding. I have tried this several different times
over the last few months, and at some point I will eventually see the
system slow to a crawl and essentially go non-responsive. I have
managed to build KDE and others that work fine, but then a simple build
of say, nmap will suddenly never end, and slowly the system becomes
unresponsive.
Has anybody else noticed this? It is certainly repeatable, but it seems
arbitrary when the problem will arise.
I have been anxious to try some speed comparisons between FreeBSD's KSE
and Linux's NPTL ... but so far, it appears that any extended test will
favor KSE on my machine, as NPTL is arbitrarily failing.
