From mboxrd@z Thu Jan 1 00:00:00 1970 From: Joe Brown Subject: Unexpected IO-APIC Date: Thu, 17 Jul 2003 11:09:14 -0400 Sender: linux-smp-owner@vger.kernel.org Message-ID: <3F16BC1A.7040504@rclooke.com> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: List-Id: Content-Type: text/plain; charset="us-ascii"; format="flowed" To: linux-smp@vger.kernel.org This is on a uniprocessor machine, but it sounded like a good idea to enable io-apic, since the BIOS has APIC set instead of PIC. Nvidia video driver warns againtst it, but I thought I'd blow smoke into that warning's face. I feel like such a newb, it sez to report this to you, so I thought I'd do that. This is with 2.4.22pre6... BTW, I'm getting better at compiling the kernel. I think I'm down to ~5~ times a day and I've only got a few unresolved dependencies remaining... If you're interested, in more info, please let me know, I'll be glad to email /var/log/messages or whatever you'd like. One question though, if it has any relevance to anything in particular, I dunno... This a P4 2.4ghz 533mhz fsb shmengie. It's dual bootable in both W2k and Linux. I run setiathome on both, because I can, but the Linux version is consistently slower that the NT version. This confounds me. I had hoped/expected the Linux version to be faster than the NT version. The Linux version is an i686 compiled/linked according to their website. As far as I know the NT version is i386. I've got this system overclocked to maximum stable as you can see here. If you have any insight, I'd appreciate it . If not, no sweat. -Joe Jul 17 08:43:51 ion kernel: Checking 'hlt' instruction... OK.
