Subject: poll(), illegal instruction and crash on smp kernel
Date: Wed, 14 Oct 2009 23:59:24 +0200 [thread overview]
Message-ID: <4AD649BC.3080905@gmx.de> (raw)
In the meantime I've got access to a parisc SMP box (J5000),
and now I think I faced for the very first time the often-here-reported
SMP kernel bug.
While this happened, I was debugging konqueror (the KDE web browser) with
gdb and suddenly I faced this crash:
Program received signal SIGILL, Illegal instruction.

Does this sound familiar to anybody here?
Does this backtrace help?
The installed kernel is Debian's 2.6.30-2-parisc-smp kernel.
Btw, the glibc is the standard (linuxthreads-based) Debian glibc 2.9-27.
I haven't yet installed Carlos' NPTL-enabled glibc on this machine yet.
